I currently have the Classic 450, RS210 and a RS212, I came from an Ashdown 410 and MK500 head. Pretty much for the same reason as you, the Ashdown cab was a mare to move on my own, plus I was remodeling the car every time I took it out.
I can carry all the TC gear in one go, all fits snugly in the boot of the car and sounds monstrous. Plenty loud enough for most gigs, if I need more volume or a little spread I go PA. As for colour, I haven't noticed it myself (doesn't mean it isn't there), but for nice deep, mellow, slightly growly blues sound it works a treat.
I also have the benefit of having a few friends with TC gear and we have managed on a couple of occasions to build the 3 cab rig, 210, 212, 112 (you can see it [url="http://sphotos-e.ak.fbcdn.net/hphotos-ak-ash3/578638_10151277741471792_307079825_n.jpg"]here[/url], I'm 6'3" to get an idea of height), and also a 210, 2x212 rig ([url="http://sphotos-f.ak.fbcdn.net/hphotos-ak-ash4/3510_10200327161718448_697913392_n.jpg"]here[/url])
