For reference, I like to keep my reels set at 25% of my line strength. 9lbs should be enough for bass fishin, unless you are in really heavy cover and need to ski 10 pounders to the boat. You might need to take your reel apart and wipe some of the grease off your drag washers.
With that being said, I never had any problems at all with my castaics. Great reel!
