If you have a buddy or a fly shop that has the new Sage Smallmouth Bass fly rod that you can test cast or test fish and see if it is what you are looking for that would be my suggestion. It only weighs in at 3.5 and is 7' 11" long and is a 4 pc. It will cast those heavier flies with no problem. It comes with its own fly line and the rod, case and fly line is around $350. You can use the line that comes with it or one of your choice. I won one in the FAOL monthly drawing and it is a joy to use and I like it. You would need to test cast one to see if it will fit your needs where you fish.
Just a suggestion and nothing more...

Fly fishing and fly tying are two things that I do, and when I am doing them, they are the only 2 things I think about. They clear my mind.
