Thanks! Very useful info. The more I read the more tempted I get to dive these waters.
As for skill level I am Advanced Open Water with 60 dives. I have no cold water experience and zero dry suit experience. From what I have read, it seems the best thing would be to do a dry suit specialty somewhere as this would enable me to try out the drysuit and dive the wreck in one dive. If I get hooked on to cold water diving (which I believe I will) then I can look into buying dry suit and environmentally sealed reg etc.
