I have had a PC for about a year now and recently for x-mas got a rotary Makita. I have used a rotary a dozen or so times before, no real problem there. My question is that I have read where some people prefer the 6" pads for the roatary due to it's ease of manuvering. The autogeek store says that the 6" edge wave pads are reccomended for DA's only. Should I just get the 8" edge rotary pads ? It would be nice to get the 6" so i could use them on my PC also, but not sure if it's okay to use 6" pads on the rotary.
