I wonder how many people would change their mind about being maskless in cold water vs warm water. I can barely open my eyes diving local cold water and it hurts. Yet in the tropics can freely swim around without a mask on and be perfectly comfortable. I have free dove plenty in warm water with just shorts on. Few would be caught in the ocean here without full exposure protection.
I made that observation here: http://www.scubaboard.com/forums/5790392-post8.html . I guess that I may not need a spare in warm water, but since I take a spare for the bulk of my (limited) diving (in cold water) I feel a bit naked without a spare in warm water.
