You're off to a good start on the Benchmade track imo. for a larger knife (4"), 806d2 or 710 would be good, mediumish (~3.5"), large ritter grip would be one of my first choices, and in the smaller 3" range (the size I find most comfortable and appropriate for EDC right now, although my 705-401 looks almost tiny compared to my 806), I'd go with a mini ritter grip, BM 707, or BM 705-401 (my current EDC).
