Move over blades, the cavity back is being more and more prevalent, even with the big boys and girls of the tour. Back in the old days, the thought was that to have good feel and be able to work the golf ball – one had to swing a club that was reinforced with solid steal from top to bottom, thus making the sweet spot the size of an amoeba’s eyelid. (Yes, I’m aware that amoebas don’t have eyelids. Don’t get smart. You’ll be using this metaphor tomorrow at the office.)

Somebody figured out that workability and feel has nothing to do with swinging a blade. It has more to deal with the size of the heal and topline. It seems pretty logical to me. If you have a club that has a thinner topline with a small heal, it is more “user friendly.” I know that I have no problem working the ball with a smaller club than one of those huge ping-pong paddle things.

With this club, Callaway has combined the things I like most about irons: The faces are small, but the sweet spot is big. So I can have all the advantages of a forgiving clubhead, but I am still able to hit high draws or low cuts, just like Padraig Harington.

Of course, Padraig doesn't play these irons on tour; these are designed for us amateur golfers looking for some game-improvement technology. Other technology includes a modified exoskeleton which distributes weight to the bottom of the club. This moves the center of gravity deep and low on the club. This really helps you get the club down to the ball (especially in deep rough) and it promotes a higher ball flight. And Wilson has made the shaft tip wider. (Man, they’ve thought of everything.) You see most with most clubs they make the actual clubhead bigger to raise the MOI so the club doesn’t twist on mishits. But in order to keep this clubface small, Callaway added size to the tip and left the club face alone. This makes the club very stiff and prevents twisting on mishits.

I recommend these irons to high to mid handicappers, and even some of you lower guys. You won't find a forgiving, game improvement iron that is longer and with workability to boot. However, for the price (at least as of February 2011) I would go with the previous model, the Wilson Staff Di9 Men's Iron Set. Unless you are that guy that has to have the latest and greatest, I don't see a lot of discernable difference in the two sets.

I recommend these clubs for high handicappers, but not beginners. (Beginners should check out Wilson Fybrid Staffs.) The DI7 is one of the easiest clubs to hit on the market. They are very reasonably priced and will provide you with greater confidence.

However, I don't like the grips that come on the irons. They are hard. As you get better, you will definitely want to replace them.

Finally, if you think you need something a little more advanced, check out the Wilson Staff Di9 Men's Iron Set. These irons have a slightly smaller clubhead and a wider sole with a lower profile blade. This is beneficial if you are getting to the level where you want to work the ball.

I grabbed a set of these for the garage because they were inexpensive and I figured it would be nice to have around for guests and family when they came to visit. I used to have a set of old Fat shafts lying around but they finally left me one day when my girlfriend had a garage sale. (Come to think of it, I haven’t seen my old Ping putter since then either, nor my box of old golf gloves, my bag of salvaged golf balls, my persimmons fairway woods, my broken tees, my stained towels, my old golf shoes and my golden retriever, “Opie”).

I decided to take them out for a trial run and boy was I impressed. First of all they are a full club longer than the old bubble shafts and way more forgiving. Because of the cavity back the sweet spot is much larger. Toe hits and heal hits traveled on target and flew the same distance as center hits.

The best thing about the set, though, is the feel. It has a very smooth feel when you hit the ball right on the large sweet spot. It’s one of those feelings that you just can’t describe to somebody who doesn’t play golf. It kind of feels like nothing at impact but the ball flies high on a penetrating ball flight. Don’t get me wrong, the set has decent feedback and you can certainly feel it when you hit a bad shot. The club has a very balanced feel and it is very easy to control your distance.

Let’s talk a little about the technology. The Di stands for distance, and they certainly deliver that. Most of the cavity weight is located directly behind the sweet spot. The ball jumps off of the face with a mid to high launch angle and carries a long way.

The club has a larger MOI then its predecessor, the Di7, but has a lower profile blade, thus giving it both forgiveness and workability. Another difference between the Di7 and Di9 is the size of the clubhead. The Di7 is an oversize, where the Di9 is mid-sized. To me, this is much more appealing, but if you are a high handicapper, I would recommend you go for the bigger, more forgiving clubhead.

Finally, I like the feel of the Di9. Wilson has added a "shock trap" urethane insert. If you are still perfecting your swing and don't hit it on the sweet spot as often as you like, then you will really like this feature (especially on the driving range on a cold day). Mishits don't rattle up into your elbows like your "old school" irons.

If you are mid to low handicapper, you should also check out the Wilson Staff Ci9 Control Iron Set. This is a beautiful set designed for better golfers.

These clubs are sweeeeeeet! I wish I was good enough to play them. PGA Tour pros Ricky Barnes and Padraig Harrington have both swung these. Ricky came very close to winning the 2009 US Open at Beth Page with these suckers. Put on your white gloves and let's take a closer look.

When you pick up the club, the first thing you will notice is the heavy, powerful forged clubhead. It feels solid enough to break out a car window. (Don't tell Elin Woods -- she is still sponsored by Nike.)

The heads look great at address with a very compact, classic look with a thinner top line. When in the hands of a skilled player, the ball flies off of the clubface with a soft smack that feels powerful but provides incredible feedback.

The clubs were made by the legendary designer Bob Medrella who has built clubs for Sam Snead, among others.

My only complaint about the clubs is the modern large "FG Tour" lettering design on the back. I'm partial to Wilson's more classic branding with the simple W/S logo.

The Wilson Ci9 iron is the third generation of the very popular, award winning Ci range. Ci stands for Control Iron as opposed to Wilson's Di (Distance Iron) series. Thus, this set is designed for the better golfer who wants to shape his shots and have a little bit of feel. The midsized face has a thin topline and a sleeker, playable look. (These are comparable to the Nike Victory Red Forged Split Cavity Irons.)

I found the club very easy to work the ball. I could flight the ball high with a soft cut or hit low drawing stingers that would run to the back of the range. The clubs are very shiny and look very cool in the bag.

One nice thing - when you give up forgiveness you gain feel. The Ci9s are very responsive and you can easily feel it when you miss the ball towards the toe or the heal. And when you catch it right in the middle – OH BABY! It has a very pleasing feel which actually feels like nothing… But the best nothing you ever felt.

In addition to the feel, the sound is very nice as well. A ball struck on the sweet spot has a crisp satisfying pop, as opposed to the dull thud of the more game improving irons. It’s like the difference between the crack of a baseball off from a wood bat in the MLB vs. the tink of those aluminum ones used in college.

Don’t get me wrong, the irons are built with some game-improving features as well. For example, there is a very subtle progressive offset and the grooves are modified U-grooves that push the maximum limits of the new USGA specifications. This gives the face tremendous spin and helps you work the ball.

There are a couple things I should warn you about this set. First, I'm not a big fan of the wedge. It's too square looking. I would recommend the W/S TW9. I'd also throw in a 50-degree gap wedge, because the PW and SW are 44 and 55, respectively. That is too big of a gap and can lead to some over-swinging – or worse, under-swinging.

Another thing is the stock grips are crummy. I’ve seen better grips on Wal-mart clubs. So when you are figuring out your total expense, make sure to budget for some high quality Winn or Lamkin grips.

Finally, I like the soft 431 stainless steel. It provides great feel and feedback, but you will need individual head covers to keep them from scuffing when being banged around in your golf bag.
