Club adjustability - more than just discretionary weighting
In 2004, TaylorMade released their r7 driver. The driver was very unique because it was the first to feature movable/adjustable weights that golfers could configure to fit or enhance their swings. Would something like that make sense for the average joe weekend player? The answer to that question is 37.65% yes, and 62.35% no. And yes, I spent hours* of exhausting research, testing and polling to come up with that precise number.
Since the introduction of the r7 and its subsequent variants, TaylorMade has been the #1 driver on tour for what seems to be an eternity, but if you stop and think about it, it makes sense as to why. The r7, particularly the r7 Quad, is highly adjustable with 4 different weights that can be interchanged to alter ball flight. More weight towards the heel promotes a draw, more towards the toe promotes a fade, and equal weighting means a relatively straight ball flight. Since there are 4 slots for weights, you can also adjust the weighting for high fades, low draws, low fades, high draws...you get the picture. A repeatable swing will allow you to fully take advantage of these adjustments...hence the 37.65% "yes", where "yes" represents touring pros, club professionals and so on. The rest of us hackers (62.35%) can use it to correct our consistent slices and hooks, adjusting the weights just once and leaving it that way, or losing the wrench, whichever comes first.
Callaway's first adjustable weight offering wasn't even adjustable. In 2005 they launched their FT-3 driver which came in 3 different flavors - Draw, Neutral and Fade. Because the head of the FT-3 was mostly carbon-composite material, a total of about 45 grams of discretionary weight was then internally reconfigured at the factory depending on what you wanted the ball to do. The Draw model had more weight placed towards the heel and the Fade model had more towards the toe. That eliminated the need for a wrench and extra weights.
In 2006 Callaway introduced the Opti-Fit system, a brilliant way to interchange almost two dozen shafts with all the various driver heads, creating a huge combination of options for golfers that wanted to be professionally fitted and matched to the clubhead and shaft that gave them the best possible combination of launch angle, distance and roll. With the introduction of the FT-5 and FT-i drivers, the Opti-Fit system looks like a science laboratory. Lots of options for everyone.

The USGA approved a proposal to make a rule that adjustments to clubs during rounds would now be possible. That change was approved and was effective for Jan 1, 2008. This meant that club heads and shafts could be interchanged between rounds. Now, I'm not quite sure how this might benefit even professionals, because I assume that all of their clubs are tweaked out to what works best for them and what fits the course, but we'll see how much they'll use these interchangeable components as the season progresses. These interchangeable parts are not just for the professionals, either.
Enter Callaway i-Mix, Callaway's venture into the latest in club adjustability that will be available to the public. If you want the benefits of this kind of adjustability, you'll need at least multiple heads or multiple shafts, plus the tool necessary to lock everything into place. While it might not make a big splash with the public due to the increase in costs, the option to make these kinds of changes now exists. To some club tinkerers this is truly a dream. Nickent has also introduced it's own system of interchangeable components as well and I imagine that TaylorMade and other manufacturers will be quick to follow this trend if they haven't already.
Golf technology continues to evolve and push existing limits. It'll be interesting to see what these companies can introduce in the future - first came adjustable weighting, and then club geometry (see Nike's SuMo or Callaway's FT-i). Now comes club component adjustability. I don't know what is left to do, but something tells me that even club FACES will soon be interchangeable. Call me crazy, but it's the next logical thing.
