I've been sticking with Fists of Thunder/Thunderclap too (level 18 here). The teleport is just too useful, especially when you're grouped with a DH who kills everything before I can see anything.
It's a shame because I really like the ability Monks get where they punch several times (eventually 10 times) in quick succession (not the one where they shoot around the screen).
I did, for a while there, use some other Spirit generating ability and relied on the dash to close the gap to enemies, but I feel I have some other more useful abilities that should be on my hotbar.
For the kick spin though I switched to the move where he drops a bell. Maybe it isn't as good as kick spin, I dunno, but I love dropping bells on people.
Also, and maybe it's just me. But Exploding Palm (Punch?) feels underwhelming even though I try to use it constantly. I think I have issues getting it activated because sometimes I hit the button to activate it but my Monk either won't do the move or it skips.
