Haven't read much about your rides lately, Trev. You can't have worn out the ST, surely.
But, as others have indicated, there comes a time when there are more highly developed bikes to be had for similar money, and we just have to move on. For years we've been farkling our bikes to achieve the level of sophistication we need and you get to the point when you wonder why. Having said that, some of the technology is getting a bit too complex, and riding will start to become more a matter of which button to push so I won't fall off.
