That's true, even with a finer diamond. My 220 kicks ass compared to a
silicon wheel.

I've been around this stuff for more than 50 years now----and have yet to
see one good reason to use silicon over diamond------for anything.

I'd have gone with the 220 as you recommended back in October but enco had a
150G 1/16" resin bonded 6A2C wheel for sale at slightly under 57 bucks. I
figure I'll learn on this one and when it wears out hopefully Norton will be
in my budget.
