I'm using a 700x38 Hyper on a one cyclocross bike and a 700x40 Schwalbe Marathon Dureme on another. The Hyper is clearly lighter, more supple and faster feeling. The Hyper is tough enough for touring, and has good traction on roads and dry gravel. The Dureme is very tough, with good traction on firm, wet gravel and might last longer. Both tires have been flat free and will last several thousand miles.
