I might be picking up a 4 to 4 1/2 pin out Heat2 pearl soon and wondering what a 1.30 label drill does with this big a pin out. With the pin close to the VAL but probably still around 3 1/2 to 4" from PAP what does this 'do' for ball reaction(eg more length/flip or earlier smoother arc)

EVERYONE wants some of this!!!
