One big difference is the addition of a new four-model structure with Tour (T) Players (P) Extreme Forgiveness (XF) and Super Game Improvement (SGI) now offered. But the real design difference has to do with the a new material used in the clubs that produces more speed and distance among other things.
Beginning on August 24 2018 the Stars and Stripes version of the Chrome Soft Truvis as well as a Chrome Soft X Truvis with the same Stars and Stripes pattern will be available at retail.
The most notable design feature of the new 0311 iron line is COR2 a proprietary polymer core material that’s 20% faster than the original filler material yielding more ball speed accuracy and consistency with the same outstanding feel PXG irons are known for. The new irons feature more of the material than in the past as well as an extremely thin maraging steel clubface improving performance across the board.
Though a lot of folks seem to think of the GAPR clubs as driving irons they’re much more than that as there are three models LO MID and HI each of which is designed to cover the full gamut of players swing types and needs.
The Spider Tour Black mallet putter that DJ has been gaming features a flow hosel and isn’t face-balanced since most pros prefer a putter that releases freely. The Pure Roll Surlyn insert provides a firmer feel than that in the Red version.
