Do you mean something like rev leverage?

I know the full rollers put the pin in the positive thumb quadrant, and cg in palm for their leverage drill.

But for a normal tracker with the PAP's that you gave, usually people put it that low so the ball will rev rather early.

My answer seems to logical. Im sure im misunderstanding something you asked.

I seen a few layouts like this in the past couple of weeks. I just seem like this layout just rolls early. I guess that the core is extremlly shorten due to the 3" deep thumb hole. I think this is a dead roll layout.
