6 kg = about 13 lbs of drag, and I assume that is the maximum. The line sizes used for the capacities are also very light. I would be suspicious about landing the fish they show in that picture with that reel!
I had a chance to pickup and play with the regular seagate, not the light and didnt like it. It looks like and feels like the new saltist spin reel. The seagate light appears to be on the kix body type which is not as good as the certatee body type. The bradia is on the certate body type and only a little bit more then the seagate in price
the PE models of those reels means its a shallow spool system as well
