So far been using Compass black extralight sizes and Schwalbe Thunderburts. Big fan of both when conditions are suitable for each.
Been riding more very steep hills lately which have a fairly loose surface so went hunting around for a fairly lightweight tyre with some knobs.
Settled on the Schwalbe X-One Allround LE, weighing 330gm. 700x35. Tubeless.
Very happy with their grip uphill. They roll pretty fast on paved also, for what they are.
