Re: Bass Fly Help
I'd advise you to stick with the rods rated line weight. If you aren't throwing anything huge, which you said you aren't, you won't need the extra line weight.
I use a 6wt for largemouth and can throw some damn big flies with it. Get a cheap 7wt line and if you feel you want to upgrade than do it. If you aren't very experienced with fly rods and lines, chances are you won't even be able to tell the difference.
