So the short answer which I was hoping would come out is you if able should invest in a Quality Lapping plate.
If you ask Utopian he can and will give you quality options at a variety of price points .
Did I mention he loves to hone?? So this would be a good time to ask and do so research based on his suggestions for a surefire lapping plate.
I/We just want you to be successful, you have chosen good hones, flat hones,shwarf free are a requisite to good edges.
Ok so, as recommended by ultrasoundguy2003's posting, Utopian what would be your recommendations at the various price points?
