The cantering was just a ... 'well, let's see how he does' thing. We haven't done a lot of it and I can say for certain our transitions weren't pretty (he doesn't know "outside leg behind the girth" yet so to get him to go involves a lot more kicking than it should) but once he got into the canter, it was nice, so long as I could keep him going. Of course, now he has to learn leads (and so do I).
I wouldn't have signed up for the english equitation (also w/t/c) class if I'd realized they'd have everyone line up on the rail and canter one at a time down the centerline. Except it wasn't "just" canter, it was "canter left lead, then a simple change, canter right lead, stop, back up five steps, then get back in line". Needless to say....we didn't do that. I'm not sure if that's typical for a class like that or they did it because there were so many people in it and they didn't want everyone cantering all at once.
Anyway, there are a bunch of pics I can post, but here's one I like of us about to turn a circle.
