the overdraw devices were interesting. some bow designs will break if you over draw them by too much.
i note that in all the shown videos of this thread, archers used not only the thumb ring draw, but the three finger western draw, and used both a thumb up and an inverted thumb down style. also the arrow was rested on the palm side or opposite on the knuckle side of the bow. both left and right handed shooters were shown. (one even appeared to be a lefty showing a newbie how to shoot left handed. hope she too was in fact a lefty.
