As you may know, I think I will send the "Hammerhead" to Pete Hogan to get it cast in aluminum and bronze.
Before I do this, I want to follow Tobias's suggestion and try the heck out of it. So I cut three brand new bandsets, two layers of TB gold, full butterfly. 12 kg of a draw (26 lbs). I will go through all of these bands tomorrow, many shots. Then I will know if the design is any good.
