Just as an experiment I glued a piece of maple backing to some Bitter Cherry thinking the cherry may be OK in compression. I did a small bend over my knee and it never came all the way back. It took a lot of set, no chrysals that I saw but lots of set. It was a very crude test, the samples were kind of narrow so there still may be hope for a cherry bow backed with maple or hickory. I wouldn't do it if I was a novice because you wouldn't know if it was the wood or you that failed. What I would do is harvest the wood and stand it in the corner for a few years. Then you would no the you and the wood are ready to give it a decent shot. I've never used soft backing like rawhide or cloth so I can't comment on them. The same goes for Big Leafed Maple. I would love for it to be workable bow wood. There is so much of it and it's so straight. I haven't tried it at all.
