I spend a lot of time on water in low light/dark casting larger topwater flies to Smallmouth Bass or mouse patterns for Brown Trout. My old stand by fly line was SA Frequency Magnum Taper in glow. Love this line for dry fly fishing in the dark and does pretty good on larger topwater patterns if not casting long distance. https://michigan-streamside.com/product/scientific-anglers-frequency-magnum-glow-fly-line-7-wt/
Started using this new line from Airflo at night and covers so much water so easy! For mousing large rivers this is my goto line – Superflo Sniper 4 Season. I’m getting ready for a week of mousing on the White River in Northern Arkansas the first week of August. In this big river will be using this line and ideal with my glow mouse patterns. Lake fishing on the back waters of the Au Sable this line has worked so good for Smallmouth Bass and can cover so much water easily.
