Well, I am finally ready to replace my Mefo and if any of you know my luck with the 908 and its severe lack of longevity (less than 1000k). I am pleased to say the 150 rear is gonna roll over 6000k with the same riding almost exactly as the 908 saw. I have to throw on my last new 908/Karoo combo for the wet spring, but another Mefo will be the summer tire of choice again for sure! The Heidi front has been a great compliment to the Mefo rear too. Not good in mud, but can really scrub speed fast on loose gravel, and its great on Tarmac too.
