Came across Rob Cosman's hand plane blade sharpening techniques and they made sense to me. I bought an Atoma 400 diamond plate (to flatten ceramic stone and rework tool profiles), an Atoma 1200 diamond plate (maintenance sharpening), and a Shapton 16000 GS (to hone and polish). Going from the 1200 to the 16000 grit was quick and resulted in the thinnest wood shavings I have ever made on my very first sharpening attempt with these products. These three products together create a very good sharpening system for woodworkers.
