What to wear under dry suit at GS?

Some of it has to do with how comfortable you are in the water. How quickly can you self rescue, and time to perfect your set up. Start off warm then shed layers if you can. Taking off my under layers while out on the ocean is something I practiced and feel 100% confidant in, but its not for everyone and I wouldn't suggest it as a plan.
What sonny did at GS6 was great at that time and he defiantly saved that guy but I would say NCKA as a whole has matured and learned a lot from its past. For Any rescue situation the first rule is don't become a rescuee your self. At big events there is usally some one fully capibable and properly trained close enough. How many throw ropes were purchased after that incident?
