My most memorable catch on fly was just a few months ago actually. Most of you have read the thread on it already located here in the
Fishing Around The World section -
Fricken Mongolia Man!!!
I was fortunate enough to spend a little time after a business trip to S. Korea and fish the Hovsgol Region of Mongolia for Taimen, Lenok, and Grayling. I landed a 33lb Taimen on a Caledon "Waterdog" Bass fly (natural with amber color tail). Amazing is all I can say. My next goal with a fly is Sailfish. I've taken many, but never on fly. When I fly fish, I don't use a Fly Rod, I spin cast flies, which makes it more difficult to control the presentation of a fly, but I think I've mastered the presenting of flies on a spinning rod.
