Mike, have you had any occurances of the wool fibers getting bound up in the center hole?

I did some testing with a Meguiar's W4000 wool pad on the 3401, and it started to melt the hooks of the plate around the hole, as well as the loop material. It got really hot in there. If I had to do it over again, I'd cut the offending fibers out of the pad. I may get this chance as my "new to me" 3401 is an route from Cali from a friend. It will be here Wednesday. Kind of excited to have it back in the arsenal!
