I use the CCS pads now and love them. I don't find that they release extra product over time, but I don't use much product and I dot it onto the non recessed areas. Whats great about them IMO, is that they cover like a normal diameter pad, but cut like a pad 1" smaller in diameter due to the recesses on the surface. So a 5" CCS pad cuts/finishes down like a 4" flat pad, while allowing me to work on an area the size for a 5" pad.
