To Jon: Size of MM neck shims?

I need to shim my EBMM Luke I guitars to be able to have the Floyd Rose trem raised higher and still have the same string height. Right now I have a neck that is very straight, but not to straight, and my string height is factory recommended. My trem is so far into the body its practically touching the guitar with the underside of the trem. Soooo…

How big are the factory installed shims that you can find on some Music Man guitars? Also what materials do you use?

Niklas
