At the moment I am thinking of a take-down lever arm bow for my guy. I'm using a 4" wide, high crowned sapling which I have cut down to 2" wide at the fades, 65" ntn, any ideas how thick the limbs should be for a 50lb draw? Also, I have always gone hollow limb with hazel as I think it helps avoid crysals but is this a good approach for a lever-arm bow (don't wanna call it molle or holmegaard cos it won't be a replica)?
