I think you'll be OK with your short drew length. The width should be fine for osage. My favorite width is 1 3/8". My newest, 53" sinew backed osage, pulls 50#+@26" easy(I tillered to 28") but I can feel the handle bend at full draw. This bow is 1 1/8" at the fades.
John, when you get near full draw get the inner limbs bending into the fades.
