Greetings jjhill and you are a tough cookie holding out as long as you did! I can handle some pretty cold water 40 degrees diving wet. Last April 08 I assisted with a AOW and to help the student feel better dove wet. It was the turning point as you experienced, I still love diving wet in the summer and fall, but when I can wear my DS with under garments and not sweat to much, it is on.
I whole heartily agree with the previous poster, get pockets and a pee - valve immediately. I waited on the pee - valve but it was a mistake. If you are going to dive dry in a cold environment no use to do so half way. Do not listen to the diaper argument check out my post on the advanced forum pee valve vs. depends .
You are going to be amazed how much more enjoyable diving is going to become.
Do not be discouraged early on diving dry it can be challenging and very different at first. Every dive gets better and before long you will be diving your suit by reflex.
Enjoy JJ keep us posted on your progress. Now your dive season will be endless and many more times comfortable.
Cam G Keep diving....keep training....keep learning!
