I, too, prefer a lower grip on a bow. The grip on the ACS is, in my opinion, the fatal flaw in an otherwise excellent bow. For me it is not so much that it is too high a grip, but that it is far too small. There is no way to hold it comfortably (for me). If you have larger hands, it may be a problem. And reshaping the grip may make the issue worse. Just my opinion. Like the bow, hate the grip! I even considered making my own riser, and using the ACS limbs on that. Also, I draw 28", and the 62" bow seems a little stiff at the end of the draw. I believe I would prefer a 64".
Just my thoughts. Take care.
