The CS27 was originally developed for durability with minimum loss of performance (CS = Control Spec), but they did such a great job in developing the tire it became a great race tire.
The RP series has a much thinner carcus to dramically increase intial traction for greater performance, at the cost of durability. Once again they did such a great job in delvelopment we ended up with high performance and durability.
The RP seems to have slightly more steering producing faster laptimes
