+100! I have the same model, and it's the best lapping plate I've ever used. The size, thickness, holes, and dual grits all add up. After the 220 and 325, I finish with 600, 1000, and 2000 grit wet/dry automotive sandpaper. I just lay the sandpaper over the plate as backing. My stones are flat and slick like glass.

That 220 can chew through any stone like a chainsaw through pulpwood when using pressure. But with light circular strokes, it's surprisingly gentle, and avoids scratching. I never touch a razor to either side, I much prefer the continuous grit DMTs for that. But it's KILLER as a lapping plate.
