Around the west coast of Canada, the dominant surfing wetsuit used to be Hotline. Now it is by far Xcel ... super stretchy, very warm. They don't last as long as they used to, maybe 2 seasons at best, but easily made up for by no longer feeling like you're in a straightjacket....they have the flex of a 4/3 or maybe even 3/2....no bs.
I've become addicted to this site http://www.whiskeymilitia.com
... which sells them for around half price. Only problem, you have to be quick about ordering, deal disappears in 10mins or once sold out. You can sign up for alerts here: http://sacalerts.com/
(warning: you may find yourself buying things you didn't know you needed.....bonus: the fashionable "sporty" women's clothes for cheap has made xmas shopping very easy for both wife and daughters
PS: yesterday they were posting a quiksilver 5/4/3 for $70, half price. I'm intrigued. No hood, so no good for winter here, but could be a good "spring" suit. Though I am skeptical about quality, when their price is about 1/3 the other leading suits. As they say, "you get what you pay for".....on that note, I've heard mixed review of hyperflex amp, with the most common being "great for the price...not perfect, but at that price, what do you expect?". For me, I get roughly 100 sessions per suit, up to 300 hours in it, I want it to fit perfect and keep me absolutely as warm as possible....I'll spend a little more for that.
