Sounds like you want a wooden bow but suspect the cherry of popping a splinter on the back, yet, don't want to loose the look of the cherry backing. This and that the cherry stave or board will be strong enough to be the poundage you want in and of it's self.
If this assumption is correct I've seen a video where a fella took a plain jane hickory bow, laid a very thin strip of decrative wood veneer on the back with smooth on, then smooth on'd a sheet of clear automotive fiberglass cloth cut to lenght and width over top of that to give the Hickory bow some pizzazz without any appreciable draw weight increase. You should be able to take that same concept of smooth on'ing a sheer sheet of automotive fb over the back of your cherry to protect it and, also, keep the radiance of wood showing through.
I've heard/read of others doing the same, as well. Check to see if youtube still has anything on this type of backing.
Hope this helps.
