Re: Not sure if anybody has tried this??
I know nothing about bass fishing (except that I've caught a few at the lake by my brother's house), but I think there might be a rod type to get you by--might have a problem with stream size in the East, but maybe not a big problem.
I have a pretty fast action 6 wt, that according to the true weight ERN (or whatever its called) rating fishes more like a 7. I fish it for trout on bigger rivers in the west, but have also done so successfully on smaller streams. I imagine that weight would also work for most bass. In saltwater, I wouldn't use it on big stripers, but could for other smaller saltwater fish like flounder and most bonefish (though not ideal on a really windy day, or for the big ones around Islamorada). Obviously too light for tarpon, permit, etc.
If you want just one rod, get a stiff 6 wt. Some, like Sage, will be more like a true 8--less good for trout, but better for salt (and, bass?). (This is only in their stiff, fast action, lines...a more medium action like a ZXL tends to be more accurately labeled.)
