More forgiveness and quieter will go farther than speed.

OH by the way, ratcheting would not do much other than extend the distance traveled by the limb-tips during the shot. Creating alot more noise and vibration. Also pushing the peak weight of the 2nd draw cycle up even higher, while the energy exerted on the the arrow would be minimally effected. Afterall, the power stroke of the shot will remain the same. Find a way to extend the power stroke and you transfer more energy to the arrow. I will post a sketch tonight when I get home.
