I've built 3 hickory cherry bows, the reason I said that I would trap is the first bow got a lot of cryshals, and failed very young, on the next 2 I lightly traped the back and had no problem, all 3 pyramids, and I know the cryshals could have been my fault but that's how I attacked the problem, right, wrong or whatever, maybe I just did a better job tillering the last 2 bows, like I said I've only built 3 cherry's so I deffer to experiance, Bub
