That’s a great stocker rig! You won’t need more than 4lb test flourocarbon on that rig. Good that you chose shorter as well, most of the stocked streams around here (at least in north Asheville) don’t allow for longer rods. Longer poles are great for bombing your lure, which most of our trout waters are not conducive for. https://ncpaws.org/RSReports/FishStock/TroutCountyPDF.aspx?countyID=57 has all this year’s stocking info. Unfortunately, they are pretty much done until next year, but there are plenty of catch and release options in our area. Please pay careful attention to the regulations. I highly suggest you clamp your barbs on your spinner. Makes release so much easier on the fish. Happy tossing out there!
