Are you sure the bow you shot was tuned. I know a lot of archery shops just slap a rest on a bow for customers to shoot, but if they have not at least paper tuned it to get it close, it was cause some vibrations that normally would not be there.

As far as the grip goes, that is just a personal feel thing. Myself, I have never picked up a Mathews and liked the grip. I might have liked the way it shot, but the grips always felt bulky to me.

BTW, grip might be the number one factor when people say they like the way a bow "feels". Grip is one reason why people become brand loyal. For instance, I love the way a Hoyt "feels". I am not saying they shot better than any other bow, but I just love the say they fit in my hand. A very personal thing that will and should be different for everyone.
