I went with Marathon Duremes because of the claimed combination of puncture protection, some off road ability and speed.The 700x35 folding tire is 475g, which is quite light for a tough tire with fairly deep tread. In the end I emphasized good performance on wet roads over off road as I'll be on asphalt 90% of the time. The Marathon, Marathon plus etc are a bit heavy and the I wanted a bit more tread, but I was concerned that the Extreme wouldn't be good on the road with it's very aggressive tread.
