On the rear of my full sus.
Have used a 2.25" Crossmark extensively in the past, loved the cornering grip and the speed, didn't like the sketchiness under braking on anything other than groomed hardpack.
Have tried a 2.2" Ikon briefly on the back of a demo bike, was staggered how well it gripped everywhere for a sparsely threaded tyre, but they're fragile or silly money when compared to Maxxis' other tyres.
Not ridden a 2.35" Larsen... What are they like by comparison? I'm thinking single ply wire bead 60a compound, matched with a 2.35" Minion up front. They look like they should be a lot better than a Crossmark on loose terrain (not mud) as they have more pronounced biting edges, especially under braking.
Not concerned with grip in mud, if its muddy i'll take the hardtail out instead. Full sus gets saved for nice days and fast rides.
