Just got back from INT US Championships in Bakersfield.
As for suit - lots of options. A dry suit will keep you warmer. You control that by what you wear underneath. Here in MI, I am still in wetsuit and will never get to drysuits because I have to winterize by then. We do, howver, take a cooler of waterbottles filled with hot tap water and douse the inside of our suits before getting into the water. That way, cold water does not infiltrate in so quickly. If it is really cold, I wear a shorty under the full suit.
As for suits - I sell a 3/2 for $70, a 4/3 fully taped for $189 (not in stock, yet, just beginning production), and a drysuit for $200. American made, American sized, and a limited lifetime warranty.
