Well, I'm quite biased, but I am still really enjoying playing a MSU cav list after nearly two years. No cannon. No hellblasters. One Steam Tank. I take 3x6 vanilla knights, 1x6 IC knights, 1x6 Reiksguard, 3x3 Demigryphs, a Lvl 4, and fill the rest in with Captasi. It can be a frustrating list to learn, initially, but you've got a lot of gaming under your belt, so the learning curve should be pretty steep. I still think it's a really fun list, because it makes the movement phase so much more interesting. I think it adds more of a strategic element to the game, when you have lots of quick units you can move quite far during a game. Allows for feints and draws, and against many less mobile armies, it really shines.
