The mold on any chip, not just
cpc can make a difference in feel, sound, and durability.
With Paulson, consider the
THC vs the
RHC. The outer ring on the
THC protects the chip and makes it more resistant to flea bites, the absence of such a ring makes the
RHC more susceptible to flea bites. The smaller inlay size on the
THC vs the
RHC exposes more of the chip to your fingers making them feel different. The
RHC feels more like the inlay and less like the chip material. Also the different inlay size have an effect on sound as well.
Similar things happen with
cpc, but with
cpc's different molds you have more at play like texture, and different amounts of material displaced from different parts of the chip, which all effect sound and feel. Inlay sizes, outer rings, different amounts of material displaced, texture [some molds are smooth (FDL) some are very textured(Amold)] and color, will have an effect on weight, feel, and sound. This is why before you spend you $$$ on a set, get samples so you can feel the differences for yourself.
Also, the mold isn't something printed on the chip, it literally "molds" the chip, so you can see how different molds will produce similar but different chips.
