I’ve been using a Hans Dampf on the front of my Hardtail and full suss for a while now. I’ve been using the trailstar ones for grip through the wet conditions of the past 11 months or so. It has good tread, a decent squarish edge, sidewalls that are just right for tubeless(snakeskin) and are super easy to tubeless. Grip is excellent although not quite as point and shoot as the fat Albert in trailstar. Irrespective of whether they clog or not, both the fat Albert and Hans Dampf seem to actually grip anyway. My only criticism of them is they’re a bit heavier than I’d like.
I’d agree about trailstar compound being very soft. My fat Albert was never the same after one day of rocky beating at CYB, where we hit everything really hard. The Hans Dampf in trailstar seems more resistant to tearing, probably because the knobs are bigger and better fixed to the tyre carcass. It’s the best tyre I’ve found to balance out most of my demands so far. The last thing that came close before the dampfs was the BC rubber queens, but their sidewalls weren’t good enough, and the UST was too heavy. I found Nobby Nics to be rather too fragile for my riding too.
