First, there are a few PGA tour players using graphite in their irons, Matt Kuchar being the most notable using the SteelFiber product. I am sure there are some Champions Tour players using graphite as well. However, just because they are using graphite, doesn’t mean they are using “light” graphite. We only carry the Steel Fiber graphite in X flex in the 110 gram. They do have a 125 gram as well. In the Recoil by UST there is the 110 and 125 in X and this year they came out with the 780 which is 89 grams and is available in X. If you truly want to go lightweight graphite in X, finding options less than 85 – 95 grams becomes a little more difficult. Paderson has the Kinetixx IMRT Kevlar 950 iron in X flex and it is 99 grams. The Paderson Kinetixx TS Series iron is 88 grams. Xcaliber TourX shaft in the TS flex is 105 grams. Most of the strong flex graphites will be 85 and up in weight because most players that need an X flex want some weight. Not much demand for a 65 gram X flex iron shafts. And don’t forget that on the steel side, weights are getting lighter as well, so the idea of wanting to reduce the overall weight of the club by going to graphite is really not the only way to go. Graphite does offer more shock dampening than steel, so if you are looking for a slight reduction in weight and more vibration dampening, then moving to graphite would be an option. But you can reduce the weight and maintain the feel and feedback you get with steel by going with a lightweight steel. The lightest weight steel shafts that are offered in X flex generally are in the 105 to 115 gram range.
