I've got a stack of hawthorn drying, and a sliver I cut off a branch as a tester. My timber came from the trunk of a mature tree and does have a lot of bark inclusions but the wood is one of the best carving timbers I ever used, dense, exceptionally easy to shape, very difficult to split and is supposed to be as good in tension as it is in compression; I believe it is rated as a first class bow wood. I am also hoping for a war-bow or two out of it. My sliver bow is nearly at brace - I'll be posting some pics soon. Incidentally, my timber does not have a dark heartwood. Oh, and it takes for-ever to season, don't rush it as it is very prone to checking due to being so dense, just leave it alone for a really long time - I think a longer drying time than yew, for instance - I did try forcing a small test piece and it split apart quite spectacularly!
