Yeah, those are a lot harder. Scissor kicks, too! My personal goal is to be able to do a decent 540 kick by my 2nd dan test (though GM doesn't require it), but that's less than 2 months away, so I dunno if that's gonna happen.
I have a few kicks that have little to no martial value that I'd like to learn to do.
I actually would like to be on a demo team, like the KTigers. Maybe not quite at that high of a level, but maybe a couple of notches below that.
