Ya gotta like 3M Ultrafina

[SuperBee364]

I've used it with the red Lc classic pads and it seemed to work fine. I always try to use the 3M ones though. (they were dirty that day)

Same here. The red, blue, grey LC pads all work well with UF, as does the red Edge wave foam. I can't tell any difference at all between the 3M Ultrafina pad and the red Edge wave foam. It feels like the exact same foam, dyed a different color.
