After reading Shooting the Stickbow by Tony Camera in attempt to improve my shooting. With proper form my draw lengthens to 30".
Sorry, I haven't read that book, but is he talking about proper form for target and recurves?
My "proper" draw length is 31" with the bow held vertical and everything lined up.
But with a selfbow, longbow, and now with a recurve I've shortened my draw to 29" with the bow canted, or any other position but straight up and down.
