I recently received a sample set of CPC chips and have been thinking about how the CPC clay differs from Paulson chips. The CPC material feels noticeably stiffer/harder than Paulson clay, and I'm curious about differences in long-term wear. I haven't seen any CPC sets with rounded bicycle tire edges, flea bites seem rarer, and warping seems a bit less common too. Do people with CPC sets find that the edges stay sharp longer than Paulson chips or that they resist warping better?
