I agree totally. The 1.5" scared me for quads but I always had some trouble with 1" and PIP. Sucked it up and went 1.5" in quad and no PIP and was the smoothest pin, yet. So I've got a bunch of 1" pins for a rainy day, and I'm going to use 1.5 from now on. both quads and glute. I haven't pinned anywhere else cause I'm chicken!
