I dunno, Ken. I rather like a worn DMT325 better. I found the Norton flattener needs flattening ITSELF after a bit.
TBH, as long as a stone is close, absolute flatness is overrated, JMO.
On my synthetic waterstones, I mostly have taken to hitting the DMT for maintenance purposes only. To get them cleaned-off and auto-slurrying properly again. I can look at the stone and tell when I am there. No need for the aggressive grid.
On ,say, my Escher hone. Since It is lightly slurried every time I use it and it is used so lightly, it only saw flattening as I first received it.
Never since.... Just me!
