Q What are the pros and cons of using full sinking lines versus ”integrated head” lines like a Teeny?
This is personal opinion, but I feel heads have got it all over full sinking lines, which I don’t use. The rear portion of a full sinking line is usually limp and heavy. If you try to shoot a fly some distance, the portion outside the rod tip has to pull a floppy, heavy line to the target. Heads, such as Teeny’s, have a light fly line behind the head that allows you to make much longer and trouble-free casts.
