Irons Buyer’s Guide 2006

If you've been delaying your purchase of new irons, we have but five words: "What are you waiting for?"

We here at Golf Tips like drivers and, of course, spend hours in the office rolling balls down the hall with the industry's newest putters. But nothing beats the thrill of poring over the latest pool of irons on our annual pilgrimage to the PGA Merchandise Show in Orlando. To us, irons are mind-boggling. They're easily the most sophisticated items in sport (auto racing aside). Just getting our heads around the technology to hopefully explain what they're meant to do in the pages of this magazine is sometimes a daunting task. But that's half the fun. Realizing the extent of a thickness variable in the toe region of the face and its effect on center of gravity and moment of inertia is about as mentally rewarding as solving the New York Times Sunday crossword in a single cup of coffee. In other words, we like it.

Hybrid Irons The all-hybrid set is making its way into the mainstream and in '06 represents key launches by several major manufacturers, including those you'd normally associate with forged blades. Also expect a number of traditional irons complete with hybrids at the top of the set.

Hot Technologies: There's a method to the design madness, especially when you consider that popular iron technologies have been developed and employed to help you on the course. Here are the top innovations and design schemes you'll find in the pool of new irons.

New Technology Low And Deep CG An oft-recurring theme in today's iron design is positioning center of gravity (CG) as close to the sole (low) and as far away from the face (deep) as possible. The advantage of a low and deep CG is that more clubhead mass lies under the equator of the golf ball at impact, thus assisting higher launch angles without the need for high-spinning golf balls. The deep CG placement is a relatively new reversal of a previously strongly held theory that the more mass placed closer to the strike area, the greater the energy transfer at impact. As it turns out, energy transfer increases as the CG moves farther away from the face. You'll see the same concept in driver design (see our May issue next month).

There are many ways to achieve a low and deep CG. Some are fairly obvious (the addition of heavy weights toward the sole) and some sublime. Undercut channels, for instance, are very effective in moving mass away from the face while also distributing weight from the center of the club to the sole. You'll find extensive use of undercut cavities (or channels) in the new iron pool.

Game Improvement Game-Improvement Meets Players' Irons In years prior, if you needed game-improvement features, you got a large, clunky club with a huge back cavity. If you desired a more traditional club, you got a tiny blade with no offset and a sweet spot the size of a pinhead. But thanks to Multi-Piece Constructioncomputer-assisted design, new materials and innovative construction methods, you can have your game improvement and classic aesthetics in the same package.

_ÊMulti-Piece Construction Long gone are the days when manufacturers casted clubs from a single mold or forged a blade from a single block of steel. Today's irons feature multiple parts, whether they be plasma-welded faceplates, tungsten inserts, urethane feel cartridges or weight-displacement bars. In most cases, multiple pieces and multi-piece construction methods are used to precisely pinpoint the CG in each iron to deliver specific launch conditions for every club in the set.

Progressive Sets Progressive Sets We like the idea of the progressive set, traditionally taking the shape of cavity-back long irons and blade-like short irons. But today's progressives are far more advanced, with not only shape variances, but face thickness, CG location, blade length, material and shaft differences to truly enhance your performance with all eight irons.

short_hosel_1.jpgShort Hosels Take a look at one of your old Hogan or Wilson sets. Now peruse the photos of the new irons in this guide. What you should instantly recognize is the difference in hosel length, which now runs universally shorter, especially in game-improvement irons. The short hosel (brought into current popularity by the likes of Callaway and PING) effectively lowers the CG (with less hosel mass above the club's center) as well as provides for the distribution of saved weight to key spots on the perimeter, which greatly aids in increasing MOI and lessens the ill effects of a mis-hit.

Vibration Vibration Dampening Feel is very important in iron play, and the last thing you want is the memory of that rocky feeling that occurs on a poor shot as you face a difficult approach. Enter a slew of vibration-reducing and shock-absorbing technologies in the clubhead, hosel and shaft. These typically take the shape of urethane-based inserts, but in some cases, the design and shape of the iron itself–as well as the material from which the iron is constructed–can direct vibration away from your hands to other areas of the clubhead. Amazing!

Advanced Sole Designs Advanced Sole Designs Advanced bounce angles, specially shaped leading and trailing edges as well as wider sole widths all work to ensure crisper contact in a variety of turf conditions. Furthermore, the wider sole shape, common now in even players' clubs, tends to lower the CG, which we know to be of great benefit in terms of helping golfers achieve the desired high-launch parameters.

_Ê Tech Talk Offset Is Good–Discuss By Don Wood For Golfers Only! GT Equipment Panel Illustration By Phil Frank"©

Tech Talk 1 The offset feature of an iron refers to the blade position in relation to the shaft axis. When viewed from the player's perspective, increased offset means that the leading edge of the blade is shifted back from the forward side of the neck of the iron. If the leading edge protrudes in front of the hosel, the iron is called "face progressed."

Average golfers and those who struggle with slicing benefit from offset irons in two ways: 1) it helps them to get the ball airborne easily; and 2) it reduces the tendency to slice the ball, especially with long irons.

Offset affects the rotational behavior of the clubhead because the shaft and CG of the head are naturally balanced to be in line with one another. When the clubhead is moved away from the shaft axis, the effect is that of more face closure as the head approaches the ball just prior to impact. This is why it's easier to draw the ball with an offset iron.

Offset also has a direct effect on CG. By shifting the clubhead back relative to the shaft axis, the CG is moved as well. Offset irons impart less spin and often produce higher launch angles, which is why offset is a prominent feature in game-improvement designs.

_Ê Tech Talk The Big Deal About CG By Don Wood For Golfers Only! GT Equipment Panel Illustration By Phil Frank_©

While sometimes mistakenly referred to as the sweet spot, the CG, or center of gravity, location of an iron is crucial to its performance. Not only does CG location have a great deal to do with the type and amount of spin an iron creates, it also directly affects ballfight, forgiveness and overall performance._Ê_Ê

Tech Talk 2 A lower CG helps to get the ball airborne by promoting a more vertical (higher) launch angle by placing the club's center of gravity below the equator of the golf ball. Similarly, a CG location that's back along the target line (away from the clubface) will impart reduced spin with a high launch angle. This combination tends to produce high, low-spinning shots that travel a maximum distance with minimal sidespin. Most recreational golfers are recommended to use so-called game-improvement irons that feature low and deep CGs for this exact reason. Long-iron alternatives (hybrids) also work very well because their CG is much lower and deeper into the head than that of comparable irons, thus producing much higher trajectories.

Another key benefit of a low and deep CG location is significantly enhanced forgiveness. Although most golfers associate perimeter weighting with forgiveness, a low and deep CG also has a great deal to do with a club's forgiveness simply by making it much easier to get the ball airborne, regardless of where on the face contact is made. Any golfer whose ballstriking and swing speed isn't strong enough to produce adequat
