Trying out my new first spey rod. Sage 12ft 5wt with wind cutter 5/6 floating. I am having problems when bringing the running line 1ft past rod tip as rio sujects. Not sure if the rod does not have the backbone for it or it is my lack of exp. When I shorten the line some I do ok. I also notice that if I bring all the line I have out straight up stream and not a U shape on a double spey I do better. Whats up?
