There probably aren't a lot of responses because this is a pretty broad question. Most of my rotary endeavors have included Optimum Compound, Menzerna SIP, Menzerna 106ff Nano, orange low profile 6" pads, white LC CCS Pads, and Blue LC CCS Pads. I will say that I just tried the LC Purple Foamed Wool and it is a lot more controllable than the orange foam pads. I also like the edge white finishing wool. If I were to place an order right now, I would replace all of my LC foam with edge. The edge system makes centering the pad an afterthought.
