Maxxis Larsen TT LUST for the (brief) summer and/or well-drained trail centres. Panaracer Trailraker UST for the winter.
Both used with sealant, fit fine on Mavic 819 rims and inflate with a track pump. As far as longevity is concerned, both sets of tyres have lasted 2 years. The Larsen rear tyre is showing signs of wear but should last another summer.
I guess though that it all depends on where you ride, how often you ride and how you ride!
