The Maxxis Tomahawk looks like it may be worth trying in the rear for the shore.
They're great tires in the dry and have tremendous cornering bite but are a bit treacherous in the wet. The low knobs that give it the low rolling resistance just don't grab in the wet. The new DD casing does the trick too. You can drop the pressure a bit more than usual and still not bottom the tire.
I rode these during the late fall and throughout the winter. The biggest factor with traction was too much psi combined with the DD casing. At 180lbs, I was using 30/28psi on 30mm inner tubeless rims. I eventually drop them down to 28/26psi and all was well with the roots and rocks on the shore. The knobs certainly don't grab the shore like a 2.4 3C HRII but the tire rolls faster, corners better, and the DD casing holds up better under rider input. Anywhere loose, these tires will excel. I see them as a very good late spring to early fall tire: dry, fast, grippy, etc.
The Minion SS really surprised me as well. I ran one all winter on the back of my Thunderbolt and the climbing grip outperformed my expectations. Cornering was fun and predictable. The tire will slide sideways right away, always, and then hook up once it transitions on to the side knobs. Very fun tire and fast rolling.
The wear on both tires, for 3C models, has been outstanding compared to other Maxxis tires. The Tomahawks have 6 months of riding and the rear is only just showing some braking wear.
