From a guy with three DE razors, I'll vote for a Superspeed. I would vote against a Knack (good with the right blade, but bad to terrible with most blades). I also have a Fatboy, but haven't used it enough to make a recommendation, though my early impression is it seems better than the Knack, but nowhere near the Superspeed.
+1 on the Progress. Nice razor. The Future is close second. Three razor sounds like restaint to me, not RAD
