I also fished C6 and got many sterlet 5-7kg on NC. Then I switched to cock bait and started getting the Persians. Got a 30kg and I fought it into the 3m corner
I would love to get a trophy one.
Hey if you are after some sturgeons, B8 hole 44:55 40clip 3X1, mole cricket or use crayfish tail. Rhino and cock were no good for me. C6 was totally dead 6 fish in 1h 30min.
