I wonder what it would be like to be able to shoot moving game like Hill. If the Howard Hill approach is what you like, go for it. The whole thing, shooting style and equipment. I used to think, as some, that starting with a recurve is better, not anymore. If your goal is to emulate Hill, do it and do it right, start with the John Schulz Hitting em like Howard Hill film, in four parts on you tube. Take Hill's advice, don't over bow, never shoot a bow that you can not easily handle.
To answer your post, is a longbow more forgiving as Hill said? If you shoot them the way Hill did, yes they are.
