Not sure what to tell you on a recurve, but I just made a bamboo backed osage that is 60" t2t. It bends in the handle at full draw and I left the bamboo a little thick (by mistake), therefore, the osage is scary thin. It sure doesn't take much osage for a full weight bow. This one is 42# at 28". I am working on the handle, now, and will post in a couple of days.
