Why I Chose the 15 Over The 21?

I have not used the 21.

My next polisher I would like is the FLEX PE8 Kompakt Rotary Polisher. Looks great for front and rear bumpers.

Maybe next black friday.

Be careful using a rotary on plastics. You would be safer using a DA like the Rupes Mini.

G21 user here. No problems so far. I have it equipped with the 5in BP and seems to work just fine. Very rarely will I use just one machine on a car.

On bumpers and tight areas I use my Flex PE8 Kompakt.

I'm not misinformed. They both use 500 watt motors. Just because the RPM range of the 15 is higher, it does not make it more powerful; obviously. With a 5" BP on the 21, you should be able to do mostly what you could do with a 21.

Thats an outrageously misinformed statement. However, if you have read the informed responses on this thread I'm certain you should be a believer on the awesomeness of the "15" stroke.
