We recently replaced the Dueler Alenzas with the Ecopias on the wife's vehicle. In short, the Alenzas were a bit too rugged for her, both in feel and from road noise, for which the Ecopias are perfect. Also was not too pleased with the significant Alenza treadwear from a vehicle that admittedly is a bit heavy, so we have to see about the Ecopia.
She is very happy with the new tires, and I notice a significant improvement in ride comfort without sacrificing much in terms of performance. This is the family vehicle, and we do a lot of miles so a balance between performance and ride comfort is exactly what the Ecopias have delivered so far.
