Just a couple suggestions that I have found that works great and does look good. My bow-tech Allegiance got a real thin grip and I also have large hands and I had to do something about this same problem.

1) Limb savers make a insulated wrap that doesn't look to bad and offers a grip. I never actually tried this but my hunting buddy swears by it.

2) What I personally using go to a hard ware store and buy Arlon tape. It is basicly a rubber tape that comes in black and orange as far I have seen but just wrap the handle. The tape sticks to itself very good and you can add more to where you want the handle to be thickest.

I am intrested in looking at those Tronjo grips closer if anyone got a site for them. Wraps and tape do look "cheaper" but when it was the only option you got they really do serve the perpose very well.

Thanks to everyone for your suggestions.

I lucked out over the holiday. While talking to a cousin, he pointed me to where I could find what I was looking for.
(of all places...... Cabela's. Imagine that! )

The stuff is called Form-a-Grip.
Starts off as a putty and cures into a hard rubber. It is usually used to make overlays on grips that conform to the hand and fingers but you can build up low spots also.

I'll be ordering a can of it this coming week. I'll post how well it works when I am done.
