That does create some very unwieldy bows if you have a long draw-and the longer it is the worse it is. I can draw 42" with a yumi and mitsugake so these numbers make a massive bow if I use your double for bendy handle. For the same value I can make a Manchu style with 12" siyahs and achieve the same draw in a 70" ntn bow. The handle barely moves on that Manchu bow, too.
You guys are making me want to make one now.
