Re: Affordable fly rod.
Welcome to the forum and flyfishing. There are plenty of nice casting rods in the "sub" $100 range. I have fished 3 in this category: Bass Pro Shops "Hobbs Creek" ($89), Bass Pro Shops "Dogwood Canyon" ($55), and Redington's "Crosswater" ($79).
"Bass" flyrod? I've caught more bass on a 4wt with size 10 flies than I can remember. Most were under 3 lbs!
I had an 8wt years ago, and gave it away...I caught more crappies on that thing than bass.
Bass Pro Shops has a line of short (7'10") rods called "heat." 8wt-10wt. $100 each. I like shorter flyrods, and my next one may be the 10wt...to chunk the big stuff for big hungry bass!
