I'll give it a go and do the 2000 side first and see if that gives me that little extra i'm always looking for,then depending on the difference in finish between the two sides i'll decide what i do with the other side,my stone is flat both sides but i can just imagine how hard it's going to be,i have thought about getting a pice of steel machined flat with some grooves like a lapping plate then hardened,might work better than ordinary lapping stones
