The big differences between the AVX and the Pro V1 and Pro V1x is the spin rate trajectory and feel it provides. The AVX is the lowest-spinning and lowest-flying of the three models and it also offers the softest compression.
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.
Other features include a thinner looking topline an angled back area for more MOI and stability and an overall more refined look. Like the original 0311 irons the GEN2 models are built with adjustable tungsten and titanium weights that can be tuned to produce an extremely accurate fit.
