IMO trailrakers are brilliant full on mud condition tyres, and that means I reserve them only for race days (honest!) – i.e. if it's a sh1te mudfest of a course, then on go the trailrakers and bingo I can ride like a mud master (yup, our team even managed to win last years SITS on them) – but they are horrid on day to day trails round here (peak district) since we don't realy get much gloopy mud here, instead we get very wet peat bogs and loads of gritty trails….
for all-round winter tyres, then Bonty MudX are divine and much more predictable through rocky sections.
Used to use the XCProMud tyres, and yes they are ok, but too hard a compound for every day use (i.e. similar to it's replacement, the Trailraker)
