I am another one to say good word about Big Game.
If I need to pick some line, my first step always is:
proof that this line is better than Big Game.
If your arguments in favor of another line are serious, buy it.
But it is not an easy task - to beat Big Game for any application!
Having said that, my second strong choice would be Trilene XL - the best mono for spinning.
Only you can solve this equation, man!
