I like the TTs - it is all I've been using so far. And here in Joburg I don't need anything else. But I am doing the Sani2c and want to be prepared for all kinds of terrain. I can just imagine last year's mud with TTs...
I have spoken to Robbie Powell at Probike (I think they are the distributers of Maxxis in SA), and he says the Ignitors have been discontinued. I am looking for the Mimo USTs.
