Weekend warrior here, used a Porter Cable 7424 for years, nice machine no complaints. Well finally decided to move up, after some research picked up a Griot's G15.

Offered to break it in on my friends Tacoma, 5 years of machine washes never seen the inside of a garage so needed some TLC. Just for kicks decided to use the PC with orange/white flat Lake County pads and the Griots with white/yellow Griots pads, doing a side by side to see the difference. Used up some full bottles of Meguiar's 105/205 I had laying around. The Griots was smoother faster and such a pleasure to use. What really suppressed me was how little dust the BOSS kicked up with the 105 compared to the PC. I'm talking a real difference! Really wish I had taken pics of the whole process, especially the difference in dusting.

Needless to say after we each had a chance doing a comparison the PC was put away, just wonder why it took so long to move up.
