Results say NOTHING. Example, Vincent Hermance could ride Tigoa tyres and still beat the crap out of everyone here. It's all about SKILL and PRECISION.
I have only tried try-all rear tyres on other people's bikes. They have folded, flexed and felt generally inferior to Maxxis. On the front though, they're nice tyres. A bit on the heavy side, but not too flexy for small rims, and plenty of grip and pinch protection.
Also, try-all tyres shed mud no better than Maxxis. They clog up really fast and lose all their grip, just like all other tyres used for trials. You'll have to give it the ol' stick treatment, beating the mud out of the tread before riding a section or whatever.
Personally though, I don't bother.
