I've done some great dives in waters that were in the high to mid 50's. When I did them, I used a 7mm 1 piece wet suit. On a few occasion I got cold to the point of hyp. I still enjoyed the dives but it took a while to get to the point where I was either warm, or too numb to notice the cold.
What I'm wondering is, when do you start to use a dry suit? Is it just personal preference or is there a line drawn somewhere?
