Hi, I watched the video with the Medieval crossbow with 200lbs draw weight [ame]https://www.youtube.com/watch?v=QXNppLFxeXY[/ame] and wondered if you could replace the 200lbs spear gun rubber with two 100lbs rubbers, to make it easier to cock. Would they both pull on the ball or would one rubber "dominate" and the other be useless? I think it would work. Does anyone have experiences with that? Bye!
