Redington has some species specific combos that include everything you need, besides maybe tippet and flies. Supposedly come with a good quality line. Got pretty good ratings. I haven't tried them.
When I lived in Iowa, I flyfished for Largemouth Bass in public ponds, and Smallmouth Bass in a small river. Caught quite a few 18"-21.75" Largemouth, and Smallies up to @ 18". Those smallies were freaky strong!
I like fast action 6wts for bass, and even ultra fast rods, if you can find them. And you can always upline with a 7wt WF line to help with casting heavier flies. 12 lb Fluoro tippet is about right for all bass.
I have the TFO BVK rods in 5wt, 6wt, and 7wt. I have some other rods I like even better, but they are really really good rods, especially for the price. And the customer service/warranty on repairs has been good, too. My only complaint on the BVK's is, in every wt I have tried, the rod sections work loose when casting/fishing. Check and reseat them periodically while fishing, and its all good. I've cast rod sections out into the water many times with that rod line. Of course you just strip them back in, no worries...just a little embarrassing when it happens.
