David, like I said on PA I built a few elm 60" static recurve selfbows(55#@26"). I hadn't used elm before these few bows and was very impressed with elm as a selfbow wood. Hickory is one of my favorite bow woods but with it's susceptibility to moisture and our humid summers I don't use hickory much anymore for selfbows but elm handles humidity better.
My elm statics did bend in the handle slightly, but I could only feel that bend when I hit full draw. Elm bends easy with dry heat but I've decided to use steam for any others I build. Elm does react well to belly tempering, especially with shorter, highly stresses selfbows.
