I have an Osage stave I've been practicing technique on. It split asymmetrically and one limb was very thin. By the time I cleaned it up and balanced the two limbs, it's about 60" long. Barely 1.25" at the handle and tapers to .75 " at midlimb and 0.5" at tip. Being so narrow, would a rounded limb cross section be better than a flat limb design?
