Had mine for a couple of months (bought from Germany). Grip and braking seem excellent, rolling resistance acceptable on the front, felt like peddling through treacle on the back! Changed the rear to the new cross king in 2.3, great combination IMHO. Previous tyre combo was DHR2 rear, HR2 front, DHR2 definitely rolls quicker on the rear than new MK, and that was 3C version! Cross King faster but not as tenacious. Mountain King on front seems easily as grippy as HR2, but more predictable for breakaway.
