What's up Erick! How cold is the water you'll be riding in? I have a 4/3 and have always had a 4/3. I do surf and the water temp is usually around 50-58 degrees year round. I have used a 3/2 but found I was more than little cold. I have used a 3/2 down south but the water was in the high 60's.
I'm all for the 3/2, but then I don't get cold that easily. I have the Oneill Psycho 2 and it makes me sweat. Guess it all comes down to how hard you're riding. What's it like in Washington? Most peeps are ready to break out the spring suit.
