Same here clive.
Had been looking towards Duratrac for my upcoming replacements but reports out there of weak sidewalls and they only sell limited sizes in Europe.
Too many sharp rocks etc.. where I play so taking no chances. Too many £££ involved.
Seems improved for snow as well:

Shredded sidewalks is my main problem, the GG AT2s have been great, with that as the only exception.
I've even cut the sidewalks on my BFG MUDs quite a bit, which is a shame. They perform beautifully when the going is soft or heavy mud/clay, I love 'em

The new BFG K2 sidewalls do look stronger, but again it only on the extended margin of the tread, they look the same in the area from the rim to that reinforced margin...

We get plenty of snow too, and they'll certainly be better than the MUDs in snow!
