I would also like to give the Edge Pads a 2 thumbs up.

I am using a slightly different version – the Edge Wave Pads – but it is still the same concept nonetheless. My favorite part about these pads is that they ALWAYS seem perfectly balanced. I'm using the blue polishing, white finishing and red finishing. I would have bought the orange light cutting pad, but I have 4 brand new LC pads that came with my Porter Cable, and I'm too cheap to buy any more pads when I've got 4 brand new ones sitting there. Bummer, because I'd much rather use the Wave pads.
Pros: Pad balance • Pads are 2-sided for more use per pad • Easy, yet secure pad installation • Can run the pad into tight spaces without worrying about the backing plate • More confidence using the PC
Cons: I'm using the Wave version, which isn't supposed to cake up like the flat pads, they are a little tougher to clean (my opinion only) because you can't really scrub them
Hope this helps!
