If you do a look up on frictional coefficients in a materials text be careful not to assume that any figure is good for the playing surface. They will give you a good general feel for the coefficient but different materials react differently with different surfaces.
good luck

That's not picky, it is correcting my (fairly significant) error.
I realized this when I made the follow up post regarding Mu > 1 but must have forgotten to save my edit (that's what I get for being on CD at 2 in the morning)
