OK layout experts help me out. I understand the basic differences between pin-up vs pin-down drillings whereas a pin-down should transition to friction slower and a pin-up should transition quicker (and I understand that is a general statement, there are always exceptions). My question is this: What would be the difference with a pin-up drill where the pin is maybe an inch above the bridge versus one where the pin is 2-2.5 inches above the bridge? Is it strictly creating a longer pin to PAP distance difference or can you put the pin higher up keeping the same pin to PAP distance? And if you can keep the same pin to PAP distance, how would a higher pin affect the reaction?

If it helps, I am a slightly speed dominant player with not a lot of axis rotation and medium/medium high revs. My PAP is 5 3/8 by 5/8 up.

Thanks!

You would not want to do that unless you have a pretty long pin distance to the cg (4-5 inches).  If you have a 2-3 pin, that means the cg is in or just under the fingers which means ALOT of finger weight.  That would mean placing the weight hole up by the fingers which would help decrease the flare of the ball and then the ball may not roll very good or it would really mellow out the backend reaction.  If you kept the cg/mb in a line through your grip, where no weight hole is needed, then you would only have to worry about drilling the fingers to China to get the finger weight out.
