I use 50lb Tuf when targeting keepers and 80lb Tuf for oversized. The braided lines have less water resistance so they stay on bottom with less weight and are extremely sensitive so you can tell if a sturgeon is even breathing on your bait. Hook setting ability is enhanced by the lack of stretch.
Make sure you run a fairly light drag if you are setting the rod in a holder. Tight drags and no stretch can mean an empty rod holder and no fish if you are not paying attention.
If you are using a rod that is not rated for 50lb line you do run a risk of breaking it, especially if you hook an oversized and have to break off. If you need to break off to avoid being spooled, take a wrap around a cleat.
Do not wrap braided line around your hand to break off. You don't want to see the results when that fish takes a run.
Good luck and good fishing.
