Just seen by GolfWRX and here’s the scoop…
V4 HB’s are stainless and feature a slot that goes through the whole head unlike the past versions where it only went partially on top and bottom. There is a TPU rubber filling the velocity slot. It’s USGA approved (of course) and early indications are the rebound/trampoline effect is huge.
Set break downs are as follows…
They can be ordered iron / HB iron / HB’s or irons and HB’s. A multitude of possible combinations with forged irons, HB irons, and hybrids. More to follow, of course.
Expected to be available in October.
