I shot an Eastern Woodland bow that had a rawhide string on it once. Pretty dang authentic, but was sluggish with shock. Still would kill a deer at close range, though.
I’ve made bend through the handle bows and really like them. They shoot better, of course, with reduced mass toward the tips. And as said before, with the handle just starting to break, tillered last.
I don’t find them uncomfortable in my hand at all but I soften the edges in the grip. Also, I don’t hold the handle with a fist, it seems natural to me to just barely grip it between my thumb and middle finger, using my pointer as the arrow rest. Can’t say I like leatherwork on “d bow” handles. They are beautiful being utilitarian. Plane Jane.
