I know we are alway enthralled with the new thing but this thread reads exactly like the Heidenau thread did 3 years ago when we were waiting them to be ok'd for entry from Germany.
We always want what we can't have. In the end our riding wont be any different with the karoo3 than it is with our current preferred tire.
Those rat bastards are probably just playing us like a drum in order to drum up demand... And I love my Heidenaus... They were worth the wait.
