I have used the Tractionator and the new Terrapactor S/T.
I was not originally a fan of the Tractionator or any other tyre they made as they were all made from natural rubber and 1 red clay hill will see you stuck. Water is a good lubricant for natural rubber so it slips easy. If you are doing desert stuff the tyre is robust and even the Tracular (soft MX) tyre in their range survived our big desert race in Australia called Finke!
The Terrapactor is alot lighter, more pliable carcus and made with butal rubber and does work better in the wet stuff. I have it on backwards now even though it is directional and I don't hate it. Tall knobs dig well, just lacks a little consistent edge grip compared to Bridgey M404's but it lasts alot longer!
