Just got a new WF6F for my Steffen and Leonard. Just fishes right. The old one just got too much mistreatment long ago.
My favorite line for my vintage 9' 6wt Sage GFL. Still fishing the original line.
I can see the fancy lines and high prices, a lot of technology in what in reality is not a large market. I can see what the advantages of some of the new lines would be compared to my old 444 type 6, for example, Shooting head for quick loading, intermediate running line. I might pony up at some point. I kinda look at things as $$$ per trip or use, but often just will it increase my enjoyment of fishing (or safety). I think that's always the capitol system choice relationship for those with at least some means but still a budget.
