Recently while helping a client select a polisher for their needs, it got me thinking that it's not an uncommon question of "what size polisher do I need or want?" I figured since I have some time today, I'd try to write a little bit about the different polishers and their pros and cons since we are fortunate enough to have some experience with various sizes.  We've worked through what we thought versus what it really is...sometimes these were the same.  Other times...we were way off the mark.
