The choice upriver sinking fly line. So easy to cast. Sinks like a stone. Easy to mend and control the fly while holding it at depth. Will actually roll-cast. After a full streamer season (all of 2019 and 2020) I made some adjustments to my upriver arsenal. While I still prefer some of the 25-foot head sinking lines for the big river, this is the way to go on tighter rivers.
