So whats the deal w/ using a 15bp on a 21? W/ the 21 you get a bigger throw but it has a slower orpm vs the 15 w/ a shorter throw & a faster orpm. So using the 15 bp & pads on a 21 gets you what? I'm just trying to figure it out. I suppose you can get in a few tighter spots & the pads are less exspensive.
