By and large, you’ll have few troubles with 200 yards, as more often than not you’ll be fishing close to shore.  However, if you hook up big and it needs to run, you’ll be in trouble. Particularly if you’ve already cast out 60 yards of your spools capacity. If you’re fishing a little lighter, and you can’t put the brakes on with loads of drag, you’re better with 300 yards of line.
