Think it's a little easier to run Duelist based around cyclone to start. Marauder take a while to get going if Cyclone is your main skill. And you'll be heading to the deep Duelist tree anyway. In my opinion, I think a cyclone build is basically a version of a dual wield cleaver build. That seems to be the most damage you'll get out of cyclone.
Running my own Duelist w/ cyclone;
build.
Dual Strike, Cleave, Cyclone, Leap Slam. Anger, Wrath, Grace.
