I have used 80 lbs braided line and tested the reel extensively for big AJ and tuna and the reel performed beautifully. It is not Stella 10000/20000, but I feel the reel is capable of handling 25 lbs drag with 80 lbs braided line though I am not sure it can handle advertizes 44 lbs drag.
I got a phone call from Shimano today that the problem with my Saragosa reel was the Knob on top of the reel was jammed when tuna made a long run at rapid speed. It was not a serious problem and there was no damage of drag system. They recommend to lubricate between top knob and washer. I know no reel is safe in my hand.
