Aha, I should have done some research before making that claim. My incorrectness aside I still firmly believe that Cyclone Strike is should be included in all builds. You could try implementing Seven Sided Strike - Fulminating Onslaught with Cyclone Strike. Maybe replace Dashing Strike with Cyclone Strike and use Mantra of Conviction - Annihilation for mobility instead.
I shall commence testing 2-hand with my Skorn! results may vary!
Combination Strike does not work like that, you need to use an extra spirit generator to get the bonus 10% damage. i.e. Use one spirit generator with another one. Which is why the Fists of Thunder - Thunderclap + Way of the Hundred Fists - Fists of Fury/Deadly Reach - Foresight build was a huge DPS increase pre 2.0.1
I am in firm belief that Cyclone Strike is a mandatory in ALL monk builds. It's damage per second per spirit spent + utility is way to good to pass. If you do take Cyclone Strike, you could change the Serenity rune to Ascension for the extra second of immunity.
I this is just my personal idea but I don't think having Staff of Kyro makes your build work. I think this can work with almost any other reasonable weapon combination. Heck Won Khim Lau + another Lightning based legendary will work.
p.s, You have Seven Sins w/ +Cyclone Strike damage! there is now NO reason for you to choose Seven Sided Strike over Cyclone Strike. (Unless you're in a group with a monk who already has Cyclone Strike)
p.s.s To further clarify the meaning of Combination Strike it clearly states that for each DIFFERENT spirit generator used you get the 10% bonus damage.
