The KMG would be nice! I'm starting to get really comfortable grinding with the edge up/spine down to set the plunge and initial grind. I was working on my little recurve, and the saber grind was coming out sick! The saber grind was following curve of the recurve edge (like your lagriffepikal but "S"-shaped), but because of the loose slack belt, I couldn't maintain saber without sacrificing good geometry and rounding off the spine too much so I ended up convexing the whole blade.
