How come, when you're fishing your flies in water with two current eddies in it, why don't your flies follow the same path? The reason I ask this is, when you watch the flies move, they don't travel through the same water, in the same manner. What governs the way the current moves.

I know you'll say the bottom topography or wind action, but, even on small waters, the flies behave the same, unless leaded. Why is this?

Could it be drag from the tippet, leader or flyline?

Natural water course decides the flow through rapids and riffles! The natural flies can if they wish alter direction! The fly anglers imitation fly is governed by the fly line drag or placement of fly by the angler! If we could only place our line to obtain that natural free flow through fast water!

Thank you lads. Of Course drag, that didn't even enter my head. Early Altzheimers at 47 eh?
