If you are ‘fortunate’ to fish in the Winter for Trout, fish a short line/leader from the tip of the rod, exploring the Czech Nymph presentation with multiple flies dredged as slow/low as possible in front of lethargic Trout. There can be exceptions of on the surface activity with midges, but overall work the bottom where Trout are holding in locations that require little effort maintain.
