I'm quite curious about these... -either foamed or completely wool - what's the real difference? -what's the cut rated at? stronger than yellow? -who other than LC makes wool pads? -do they have velcro backing? -why do the finish so well? -how's the buffer hop on them? i don't know how these work, so i would expect that something that doesn't have much cushion to be terrible to work with. However, a lot of people seem to love this stuff. I'm looking to get some wool pads because I am not too big a fan of the LC pads. The orange is too stiff for me, and the others are inferior to the 3M ones from my experience. Any input is greatly appreciated! Thanks in advance!
