My examples, that i use frequently : Jab+left highkick coming in at 90 degree angle. Jab , then put my right hand on opponents eyes and then i do a right high kick in sort of jumping back downward style (watch pettas vs aerts or bonjasky vs akebono, for examples). Low kick while looking up, then i do a high kick while looking at his legs, as if i were to low kick him. While the opponent is in the corner of the ring , side step to the right , the opponent will naturally try to go left , then kick with the shin to the head with the left leg. Then of course there's the brazilian kick , its done by faking a front kick then going for the highkick. I can give more examples but I find these the most useful, oh and wanaka has a good setup i saw in his fight, jab to the body then highkick. For highkicks i find it most important to make the kick come sort of from the side, and sometimes you have to sacrifice your full power for accuracy. Throw in your examples.
