I'm trying to understand the relative value of each of these types of lines. I'm currently using WC on Sage Euro's or a Winston LT and find that they work just fine. I've never used a Long Belly. The longest line I've used is a Mid Spey. The rod I use are 6-126 G IV, 8-124 G IV, 10-140 (old GFL), and Winston LT 9/10 140-4. Am I missing the boat here? I usually fish the Clearwater and Grande Ronde. Thanks for the input.
