Echoes have received good reviews, no personal experience, but I remember Fish and Fly gave the 5 wt very good marks against all the high end rods. I went to Rajeff's site and the Echo2 has been superseded by the Edge, maybe that's what should be researched. Harry Koons couldn't say enough about the saltwater models, said he liked them better than his Sages, sadly invoking his name.
Our tradition is that of the first man who sneaked off to the creek when the tribe did not really need fish. Haig-Brown
