I've got a couple rods that seem to cast fairly well when underlined. One of them a TFO 4 weight - The number on the rod usually refers to a Double taper line-but I've tried it with a weight forward 4 and it's fine - until the wind picks up. It's much better with WF5. Overlining tends seems to be more useful- same 4wt rod w/ WF6 does a passable job lobbing streamers. Good luck. mountainjam
