Buy it if you want it.
Just remember that small bikes are so much less effort and much cheaper when they fall over.
The AT would be brilliant on the longer rides and a bit of a pain going to the cafe.
You fall over a lot when going to the cafe? 
Don't you just know it!

No, I enjoy fairly technical slow stuff, where falls, scratches and bumps are the norm.
I've seen you, Hardy. You make that AT look like a 125, so it's unfair to project your easy handling of a quarter ton bike onto someone of a little more than half your weight.
And Dux, you know what I mean. It's much easier to move a little dirtbike in and out the yard, to bump onto the pavement and slip through narrow gaps etc. You can knock panel pins in with a four-pounder, but it's just easier with a little upholstery hammer.
I've ridden the DCT and it's a truly great bike. I'd buy one like a shot if I needed one. But right now my little bike is all I need.
