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.
