I bought the Psycho Tech
"I bought the Psycho Tech 4/3 as a complement to my Hyperfreak 4/3 that I've had for about a year. I use both for kitesurfing. Both suits are L. I am 6-0, weigh 180 with a long torso, and short fairly muscular legs (31") inseam. They are both awesome suits, but very different, and I am glad I have both. The Hyperfreak is stretchy and super comfortable and I use it when either the water or air is a bit cold, but not both. it is easy to get on an off. Even though it fits great, and my calves are pretty big, water will sometimes collect in the lower legs. I take out the Psychotech when the conditions include colder water and air. The rubberized wind panels make a big difference preventing heat loss. It IS harder to get on, but I wouldn't call it "stiff" at all - it is still super comfortable, and stays locked in place. And water doesn't collect in the legs. I've been out for some several hour long active sessions when I've spent plenty of time in the water, and it almost seemed dry inside the suit. My other suits are 3/2 shorty and full 6/5 hooded winter suit. Both of the 4/3 O'Neills are perfect in between."
awesome
"AAAA++++"
Not flexible.
"Great timing. This is the most restrictive suit I have ever worn. The rubber has no flexibility. I felt like I was in a straight jacket. Ur Hyperfreak line is 1000 percent more flexible. The Psyco Tech is not wearable. I tried it for the 1st time today. I will never wear it again. It's horrendous. I switched to ur wet suits 2 years ago after decades wearing Rip Curl suits but they only lasted 3/4 of a season. I love the hyper line but the Psycho wetsuit is a bust. The only positive is that it was really warm, but what good is being really warm if u don't have maneuverability. This would be a great wet suit for water filming, sled riders, and boogey boarders."
