Russ im looking at those grooves and I think they are pretty darn close. If it fits well in your hand I believe it will fit well in mine. I know the sample bow fits well in mine and that was designed for your hand, so if its anything like that its fine. Speaking of the sample bow...it being shipped back tomorrow to you.
Man i cant wait to shoot that bow. It is looking great brother. Something tells me your gonna be asked to build quite a few more of em. Then finally you will have to actually work. LOLv
