I'm certainly tempted to try the Mefo's next. I'm running an MT43 rear right now and liking it, but there's no way it'll see more than bout 1,500 miles before it's toast. No happy with the front tho' - another Pirelli (MT21, I think). Doesn't work well in the dirt.
Finn - any particular reason you went with the 140 over the 130?
