I actually don't really care of the finer dmt diamond stones or the ez lap stones. I gave my ezlaps to a friend and bought the combo dmts.
I use the course on the duo sharp course/extra course dmt
And a 1000 grit shapton
Finally a strop with the green compound
Blade is razer sharp in < 30s if there's no major nicks in the blade. Major nicks mean going to the extra course and grinding it out for a few minutes first.
Every other system I tried just didn't work as well or as fast. The shapton just seems so much faster than the finer diamond stones.
