Check out this video I did with Tim Cammisa from Trout and Feather. We discuss my favorite fly lines for smallmouth and a general overview on what to take into consideration when choosing a line for smallmouth bass. I will say one thing, the SA Bass Bug does not come in a 5wt if you are going to down line a 6wt rod, however the Titan Long does come in a 5wt. It is basically the same line without the hot water coating, I have not had any issues with that line in water up to 88 degrees. Check it out and give the video a like!
