My PAP has changed over the years, but it was 4 x 1 and I had a LT-48 Gold with a 6" pin. The pin was actually left of my middle finger hole by about an inch. I drilled that ball up for bowling the high-roller when I needed to play "over the cap" on the left side of the lane. I got tremendous length and tons of backend. Of course it was too wicked to use on oil, but great when I needed extra angle on a broken down pattern.
I wouldn't recommend placing the pin any further than 6 1/2" from the PAP. So, for someone who tracks extremly close to the fingers and thumb who may have a PAP of 6" x 1/4", that pin may be too far from their PAP and COULD cause the ball to flare backwards.
So, where the pin is in relation to your grips/fingerholes tells really only part of the story. If the holes were drilled into the top of the weight block (pin down) or side of it (pin up). If you drill the pin down, and into the top of the block, you are essentially making the weight block (core) shorter and lowering the RG, which will cause the ball to rev quicker. If you drill into the side, you will make the core essentially taller, raising the RG and getting more lope, or skid.
