RE:No. Shore, How Long?
For choosing fly and line types I consider two things: 1. The depth I want to fish and 2. The speed of the retrieve. (Current increases the speed of your retrieve in relative terms.) If I'm fishing shallower waters I will generally not use a sinking line but if I want a fast retrieve near the bottom a sinking line and weighted fly is the way to go. I have learned to not be shy about switching my spools around to match the conditions. It only takes a few moments and the payoff can be great.
