I swap around a bit so at present I have a Minion on the front and an Ardent on the rear, when the trails get muddy, as opposed to their current damp status, I’ll go Minion on the rear and Shorty up front. If it’s a really wet winter I’ll run Shorty front and rear.
Shorty is excellent on the front if it’s muddy but quite draggy on the rear so it needs to be very muddy to have it on the rear.
I leave near Winchester and the ground has a lot of clay in it so when it’s really muddy it’s the thick clingy stuff so it needs an aggressive tread.
