My limited experience with them has not been very good. I have been trying the Lake Country style. Only used the DA ones on my 3401 once and honestly I did not have enough experience with other pad types to really compare.
I have tried the rotary style on my PE14 Flex a couple of different times. Those times were all on single stage type paints of various styles (powder, gel, etc,) I tried with both FG400 and PG1000. All of the times I tried them, they cut fast, but for whatever reason they bite way too hard and make the machine uncontrollable. Unlike a wool pad or foam pad, they seem to "grab" the paint and walk the machine in every direction even with no pressure on a vertical panel. When you attempt to control this, it takes some strong arms and a little bit of downpressure, however once I have gotten it under control it will stall out the Flex. I was running the Flex between 1000-1200RPM or so. I would only ever do one section on each of the 3 vehicles I tried it on as they just were not working.
I think maybe they are a good choice for a more agressive pad for the DA machines, but I'll stick with Wool for heavy cutting on the RB.
It could be the LC brand pads too. It sounds like a lot of people have had good luck with the Megs and Surbuf pads. Maybe some day I will try those, but for right now I've got plenty of others to get some experience with and formulate my opinion on.
