I'm not set on one brand, years ago I used Aircell Supreme most of the time. I have cortland 444 on my 4wt., Wulff line on my 8/9, On my 3wt. I only know it's DT because I had to get some one to order it because everyone went to WF. On the new rod I built I have Cortland Fair Play, thats about as cheap as you can go, $12.95, I'm testing it to see what size line I'm going to use and have no complaints about it, thats the line I'm useing today. I fished more this winter than I did last summer, and it was a cold winther. when everything is freezing up it's a lot harder on your line. Most line will last me a long time.
