Can you give any first hand pro/cons compared to others in the 38-42 range you have tried? I too am always in search of all purpose tires in this range. I swap between a Hutchinson Overide 38, Conti SpeedRide 42 and a Riddler 45 depending on the overall terrain. The Terra might be a good compromise between the last two.
