Probably already been asked and my apologies for that. But under the search I was unable to find anything. And I'm green to this beautiful wealth of knowledge. This is my first post soooo let me have it! I've got a redington cpx 11'3 7/8 weight switch rod, fishing a variety of rivers(most small to medium) indicator nymphs with a tiny bit of swing(still learning) pretty new to Spey casting, what kind of line do you recommend? I was heavily leaning towards rio switch but what grain?
