Hey wdc, welcome to the forum-
I think you'd be better off with a lighter weight rod too. An 8'6" or 9' 5 weight sounds about right for trout in the hootch if you're looking to pick up another rod in addition to the 6/7 weight South Bend you have now. A 5 weight will be great for trout, panfish will stiff be fun to catch, and you can throw some stuff for bass with it too.
And if you want to throw bigger wind resistant flies for bass like big poppers or bass bugs, you can do that with your South Bend rod with a weight forward 7 weight line.
The good news is that there are a ton of good choices out there whatever your budget.
But in the meantime, fish that South Bend too since that's what you have. To keep things in perspective, it might be helpful to read Ard's (Hardyreels) post about taping a fly reel to a spinning rod, lining it up with a fly line and using it to catch the heck out of fish in Alaska on a recent trip:
