I have got a frame which I'm hopefully going to build up 97/98 period correct (I still use the 1997 Profile cranks and Pitchforks that were on it!)
Semi tempted to sell it but I know the Mk1 Trailboss was quite a rare and sought after frame and I'd probably regret it the moment I let it go! I'll keep my eyes open and let you know if I do see or hear of one for sale.
Know what you mean about the STA, was just slightly too burly compared to the Trailboss!
