the ones I made were longer,, not quite as a dramatic bend as some of the Native bows,, I think I was just lazy, it was alot of wood to bend,,

and I could get a pretty good straight limb bow to shoot well,, I think if your gonna make one,, the shape will hold better if you sinew back it,, but I think you will enjoy the build and shooting one,,check out Jim Hamms first book,, bows of the Native Americans, he makes a sinew one in there,,
