Not a pain. This is a place to ask questions.

A 5wt with a sink tip or intermediate line would be workable when the surf is low -ankle breaker conditions. I sometimes use a 5wt in the bays too.

I have fly fished San Diego bay from a borrowed kayak. I enjoyed it enough that I intend to acquire a yak later this year. A boat would be better but I can fit a kayak into my budget and I don't have to pay to store it anywhere.

There is a pretty good book by Ken Hanley titled "Fly Fishing the Pacific Inshore" that covers surf and bay fishing strategies that apply to our local waters.
