Thanks for the input. My Wife is very cold natured and routinely wears a 7mm and a hood and vest when I am wearing a 5mm. I am unsure how long she would be able to stay in the water at spring temp of 72 degrees. I have heard from my Cave Instructor Paul Heinerth that the air is warm and does not make you cold like OC. According to Paul they did the whole Peacock system in 3 hours. I am not sure what they mean by the whole system but knowing Paul it was probably pretty extensive. In general does the OTU count keep you out of the water before you would be able to make 7-8 hours of diving in one day (i.e PPO2 @1.3 2 1/2 hours around 200 OTU's).
In other words extremely deep diving for an extremely long requires a large scrubber. How common is multiple hours diving multiple times a day?
i definitely find it a lot warmer on the loop than OC. this last weekend was the first time i really felt cold but i was a little under weighted for my dry suit. I can dive for much longer than i used to be able to.
I'm no caver, you should defintely get imput from the folks who are, but really if you are planning on doing overhead stuff for three hours at a time you definintely want plenty of extra scrubber time for possible complications...IMHO....again, just makde double sure you are not going to need the longer duration of the inspo.
