krispy, you want to get a 3mm or so farmer john, with a 3mm+ shorty to go over it. wear the farmer john alone in warmer times, and add the shorty when it is colder. if you end up getting a suit for next year, let me know.
i am not looking to do all out skishing, yet. as krispy guessed, i want to get a little further out to a few rocks. the point about the waders filling up being more dangerous than wearing a wetsuit is true. if the waders fill up and you can't get them off, you drown. with the wetsuit, you do not have this issue. like all other aspects of surf fishing, you must still use your head and stay well within your limits.
