Lovely pic, JenM. Stripped down racing exotica is all very well, but that's that sort of picture that really inspires me.
My XTC frame (a bit older than yours, and shamefully abused over the last decade) is being resprayed at the moment. I really like it. It's supremely comfortable and just handles everything you throw at it without drama. I've done several camping trips with it loaded down with crap, and it just takes the weight in its stride. I agree that it seems to prefer a load, if anything.
It's nicely made, as well - Thorn got this one right, I think.
