Polycarbonate wont crack.
I haven't tested tham for scuffing but how visible scuffs are would surely depend on the colour of the plastic used, i.e. on black they would hardly show.
They would probably be heavier than Correx but as they're only 2mm not very much so.
They will come will holes pre-drilled with the spacings to suit various numbers of spokes. You can then secure them with a set of screws. I may be able to supply these too if price is not too prohibitive
