For panfish, anything 3-6wt would work well. Add smallmouth to the mix, get the 6 wt. 9ft, 4 pieces. The 6 is better at throwing poppers and closers, then handling the odd big fish.
I have Cabela’s, Redington, TFO, St Croix, Orvis, Sage, and Winston. Go with a Redington or TFO, whatever is cheaper. Avoid cheap Cabela’s, they have a nasty habit of breaking in the tip section during a cast.
I suggest 4 categories of flies: poppers/sneaky Pete’s/gurglers to throw in calm water and let the ripples dissipate. Might take 20-30s for a smallie to come up and eat. Then clousers in chart/white and whatever other color you like. Then some kind of crawfish pattern to drift in current or crawl on the bottom. Finally, wooly buggers of some flavor in white and black to strip or drift, size 4 if you can. Cone heads are handy.
