I usually start my day of fishing with some dry or streamer. Are my favorite ways to check the water.
However, when I decide to go with nymphs is always a hard decision to use strike indicators or not. Many years of fishing and I can't say if its better with or without them. I feel that a long fluoro leader, a correctly weighted nymph, a split shot and good control (cast short as possible) do the job fine.
Guys, do you use s.i. or not?
Good fishing!
