Hey, I love kicking (and punching, too) -- I've been training in other arts for years now, but once a kicker (and puncher)... well, it's hard to get it out of your system.
As long as you practice with other kickers, then sure those high kicks have a good chance of serving you. But I gotta tell you -- the guys I train with now will take you apart if you try it (and so will I, know that I've learned some of their skills). In summary: Don't try high kicks with highly trained grapplers!
I sure do love watching first-rate high kickers, though. It's a fine show of athleticism and coordination.
