I don't think that is the point, I know what 15kg of drag feels like, but as the tester at
http://www.alanhawk.com/ said it was used on 10kg before it had problems, not intending to lift 15kg vertically up on a spinning rod, but if I lock up the drag at 15 kg and hold the rod straight inline to a large fish heading for the horizon then I would like to get that 15kg of drag as advertised. This is assuming that the fish is far enough away from the boat that this is even possible. Either way the reel should be capable to deliver what it is advertised at.
