You're going to have to use an indicator unless you high stick. Single hook only on the Salmon River. This means no dry fly as your indicator. Unless of course you cut the hook off.
You're all snaggers.
Don't waste the money on a new setup if you aren't going to be confident fishing it. Just stick with what you have and go from there. You can swing flies with a single hand rod, just the same as a two handed rod.
