If the target is big fish, I'd wait until at least May 15.
I keep a great big jar of goodwill on the shelf that gets filled between November 15 and May 15. It would be a sin to let any of it leak out too early..
Still been hitting freshwater though. I did have a fish close to 20# last weekend on 6# line right up to the boat that was hooked on the tail...twas a carp.
