Just got back from a 1,700 mile ride. My E3's were great in all road conditions (tar snakes, ruts, sweepers and twisties) and excellent in the rain...hard rain! They also did great on the Mackinac Bridge which is mostly metal grate at up to 200' above the water. Ran way better then my bud's 402's.
I have found the Metzlers to be the best tracking, wet traction and handling tire so far...
They are a little softer which may cause them to wear a little quicker. That depends on your riding style. Far as I'm concerned the rider is supposed to last, not the tire.
