64p gives a smoother operation, but needs to be closer meshed, and is prone to debris.
48p is not as smooth but also does not need to be meshed as close, so is better for where you may be prone to debris getting in to the spur teeth.
Normal rule is 64p indoor 48p outdoor
pitch rating is not as noticable on a pan car than it is in a Touring car.
(i still run 64p outdoors and bitch about the debris
)
