Made several from it Guy,debark as you said you have done,bugs love it,seal it really good,prone to check,don't cut into to small of staves as it also tends to twist as it dries,make sure it is really dry before you start tillering as it tends to be slow to dry.now other than all that which really ant that much ,it will make a fine bow and the wood is beautiful when it is finished,almost takes on a purple color.
Maybe a little wider and a tad longer than Hickory. 66 n-n 1 5/8 to mid limb tapered to 1/2 or less at the tips should make a 50 +@ 26 or so easily.
One more thing.watch out for any knots in a hard bending area,they tend to go deep with lots of dead crap in them,also keep in a dry area,like any white wood it will dry rot on the outside very quick left in the element's.
