Depends on how and what you ride (like I need to tell you that), I ride light and fast, and love the Conti Twister Supersonic with Stans in UST rims, 370 grams, YOW! Yeah, they are weeny light, and very thin, but they feel like you bike just got a hit of meth. (no illicit drug plug intended) If you are a high flying, fast downhilling free rider, these will not be your choice, but for railing the trail at high speed with nice cornering, and great traction these are fantastic. That said, I run that in the back, and a Specialized Team Control in the front for uncompromising front end cornering, the Conti Verticals will be my next front, as Spec does not make these tires anymore. I ride in the northeastern US, lot's of mud, rocks, and technical scrambly climbing. I rode the twister all last summer (wet and soggy) and it was great, if you are a power stroke pedaler, they will break free in the slime, but if you can modulate your power in those situations, you will be rewarded with more traction than you thought possible from a semi-slick. Everyone I sell these to has the same reaction. These are also available in thicker skinned, more sturdy options, like the Protection, and Pro versions. Rock on!
