My first day of class was more techniques (other than Fridays, we don't do much conditioning in class...that's for us on our own at home).
My sabomnim rarely flashes his stuff. I've seen him do some moves and stuff that are pretty cool, but he doesn't really feel the need to showoff so I rarely see him do more than he's teaching us, so I don't see him doing a flying, spinning, jumping, whatsitkick, just a really, really, really good sidekick or roundhouse (or whataver he's teaching me).
Also, it takes a while to understand what you are really seeing. A roundhouse looks pretty simple but there is a big difference between 'just kick' and 'kick really, really well' and unless you are used to it, it's hard to see the difference. I'm mostly impressed not by what the BBs do, but at how well they do it.
