Hi there Rooski. Looking at buying x2 Pure Drives from one guy at the club that has basically never used them. On Saturday I held the PD 2015 of this guy with 4 1/4 grip size in my right hand and the 4 1/4 grip felt bigger to me. Is this in fact true? Is it not just the grip that is thicker on the Pure Drives or is it a fact that underneath the grip the actual spung is bigger? Thank you
