Kinda agree with GW 🙂
High rollers or Minnions are fine in mud (unless racing as said).
For trail riding i have always been against any type of mud tyre due to the damage they cause to natural trails,
At the end of the day they cut into the ground to grip, no one can argue they don`t do that, just look at some trails here in the Pentlands, or other peat based hills, Unfortuantly some folk do not seem to care about that to have zero slip and max grip,
Also you can`t beat a bit out of control 2 wheel slides to raise a smile riding in wet conditions 🙂
