I'm 6'4",and I've been shooting at 30in.for years.I've always had to shoot with a big bend in my elbow,plus,I had to "cock" my head a little.I know this sounds wierd,but thats the way I shot.
Len(in Maryland) is helping me out.He feels that I'm really a 31.5 draw,so he's going to set up an Old Glory for me...Bob
