Rode my Titus Fire/Fileline on familiar, dry singletrack for the first time last night.
It's not the same as a 26er (surprise) but it is nicely different. I think I could really get to like it. Extra length of the bike is an issue sometimes in the tight stuff but it's far more forgiving of small roots on apexes and stuff.
Dropper post helped as well, I think - was nice to drop it a bit so I coudl still sit and pedal a bit but not having it in the way going over logs and stuff. Fully dropped - I don't have the legs to stand up and pedal/not pedal for long enough
Those On-one tyres are pretty good too.
