If you fancy trying out a fluorocarbon reel line this winter this new Shimano Aero is as good as any I have come across. It is super quick to sink, has high abrasion-resistance, and is just about soft and limp enough to not keep jumping off your reel spool in annoying coils. Who knows? It may even get you a few extra bites in clear water when the going is really hard. In 0.30mm (12lb) and 0.35mm (16lb).
Price: £34.99 and £44.99
