Steve, with 50lb your just stressing your gear. The confidence factor that you get out of 50lb braid (which actually breaks more like 75lbs ) may cause you to put a touch more hurt on a bigger fish than you normally would with less drag pressure and lighter line. That translates into pulled hooks, at least in my experience. I use 50lb on my conventional tackle at the canal but for plugging the Elizabeths I use 30lb and on the beach 20 and 14 no matter how big the fish are (or aren't more so these days). 30lb braid will land a small whale if you had enough line and you can put a lot of strain on it.
The lighter lines make me use a lighter touch. Just because you can get a fifty pound line with a very small diameter and pack it on a reel, I have found that it isn't always a good thing.
Another of my hair brained theories!
