Hey Stan,
I dove a lot in Puget Sound, and if you haven't found out, the waters there are a bit on the cool side- where I dove the water temp averaged low to high 40s. I would get really cold in a 7mm suit, and my face would go completely numb within a minute. Unless you have no nerve endings you may want to reconsider purchasing something thicker than a 3 or 5 mil like you mentioned or you won't be staying in the water for long.
There are lots of good wrecks out there between 30-60 feet deep, and most have a good supply of shootable fish hanging around them. Good luck.
Thanks for the info Sames! Definitely gunna reconsider a thicker wetsuit! If you don't mind me askin..can you fill me in on some of the other gear you used?
