My experience with chrysals have been on hickory and a osage limb bow. The osage was poorly tillered by myself, but a patch and I was out to shoot it again. Took a young doe that fall with it. Still shoots 15 years later.Black locust bow I have, wide limbs, 68" long has several frets or chrysal on lower, working part of limb. Still shooting. took a big doe with it last year and some squirrels. It might fold up the next time I string it, but I'm not cutting it up! My oppinion, tillering and where the wood grew or how. I love black locust, hickory, was it pignut, butternut, shagbark, might make a differnce! Good shootin steve.
