i can answer 2, maybe three of those. stacked leverage is 3 3/8 by 3 3/8, the most unstable drilling available and one of the strongest (not earliest) drillings available. 315 (not 360) is where the cg is up and to the right of the pin, in negative 45 degree ratio from the pap to the pin to the cg, if that makes sense. this is supposed to give a very controllable read on the ball, and is supposed to be forgiving

axis leverage is pin on axis and cg in the leverage position. this drilling is supposed to roll very early. i dont know exactly what the leverage position is, but i would guess that it is stacked below and has a pin out of 3 inches? this doesnt really make sense with the way it would throw off the static weights, so im probably wrong. usually i just go by degrees, area of pin, mb placement, static weights, and inches from pap when talking about drilling, as all of these have an affect on reaction.

So if I wanted a skid/flip (snappy) ball, I would wanna drill it stacked leverage? I mean, obviously the type of ball, and the bowler come in to account here, but again, generally this will give me length and a hard backend snap?
