GUE has a drysuit class? I thought if you didn't own a DUI with a WKPP 25 years patch glued on they didn't even let you in the club!!!!!
Drysuits are awesome. They'll literally change the way you dive. And they also make casual conversation about gluing things onto your private bits completely acceptable to talk about in public.
If I can't dive in board shorts and a rash guard, I'm in a drysuit. It takes a little bit to get comfortable, but like anything else, once you spend some time in it it becomes second nature.
