Wow guys, way to not help a newer guy out at all. I dont like posting much but i hate to see a logical question go unanswered after two pages of unhelpful comments, so heres to the original poster, whose asking what the raection shape difference would be by having a pin up a pin down and one in between, and he did say all of which would be the same pin to pap distance, so i dont see how you guys can argue that theres not enough info to at the very least provide a vague but accurate answer.
Answer: keep in mind theres two different core shaped balls, sym and asym... But for this question it doesnt matter since all your doing is changing the VAL angle. The pin up would have the smallest VAL angle, the pin down the largest, and obviously the pin inbetween would be somewhere in the middle in terms of VAL angles. The VAl angle controls the length of the second transition of ball motion. Therefore with all other variables being identical, especially pin to pap, as stated. The pin up (smallest VAL angle also known by storm as pin buffer) will transition the fastest. Meaning its going to go from its hook phase to its roll phase the quickest, which often times can look like more of a hockey stick, or asharper angular motion off the break point, but sometimes will lack continuation thru the pins when not used on the right combination of lane surface, oil, or ball choice.. Thepin down ball (largest of the three VAL angles or pin buffers) will transition from hook to roll the slowest which will be a smoother more continues arc many times vs the snappier quicker transition that was seen with the pin up.. And then obviously the pin inbetween will provide a reaction inbetween the two.
Hope that helps
