Hey all - I've got a 2011 Martin Onza 3 and the grips are stock bare aluminum and by golly they get cold fast and they suck the heat from your hands faster. I've shot my buddy's Matthews and I enjoyed the grip primarily from the perspective that my hand didn't freeze. Does anyone know if there are/were grips made for my bow or if I just need to either buy one and modify it or make my own from scratch (either leather or wood). Thanks
