I ve been studying that book,, he doesnt like deflex either,, as you can see he has induced reflex in the handle, that seems to not be popular so much now,, but I like it,, and think the bow probably shoots as well as most well designed bows,, I have not made one,,
He mentions quite a few times that the Sioux liked shorter bows, shooting 23 inch arrows,, it takes skill to shoot a shorter bow and arrow,, but there must have been advantages for them to settle on those specs,,,,
