bib,
>My point was, you need to move the area of the bend up and down the shaft. You don’t need to move the fulcrum during the set, but each set should have a different fulcrum point. Also, you want to do Vs and As, stressing top and bottom, and also turn the shaft on each side so that too much stress is not placed in one area affecting minimal tissues.<
Why? Why not blast one area of the tunica and stress that until it is fatigued, and then move the fulcrum?
