Here's a pic that shows the difference between that Shrew Hill, a HHA Cheetah, and an HHA Halfbreed:
The bow on the left, the Shrew Hill, fit my hand perfectly. The middle bow was okay, but I like a straight grip better. The bow on the right, has a very small grip. I built it up with some layers of leather and wrapped it with leather thong. It is still too short, as my hand completely overlaps the leather. I've shot it so much that I'm accustomed to it, but I do have to make sure the front edge of my fletching is glued down tight (having a feather slice into your hand hurts). It also precludes me from using a glove on that bow hand.
Oddly enough, the bow on the right is my main hunting bow. One of these days I'll get around to ordering another with a grip that fits me.
