I don't really understand the concept of a "heavy hit" in a swinger's action.
Here is a link to a golfer performing a left arm swing.
This is presumably drag loading at its purest. Does he have a "heavy hit"? What would a swinger need to do in order to have a "heavy hit" if PA#2 releases passively/automatically according to the principle of the endless belt?
