If I had all the time and money I would buy them and test them all, but I simply don't. I use mainly menzerna products for polishing and compounding needs. I have a dewalt rotary and a pc. I like to use lake country pads for the pc and edge pads for the rotary. Any suggestions or preferences for pad use? I use menzerna compound, super intense polish, and nano polish. I really would like any input you can provide. Thanks!!:getdown
