For what It's worth, I also surf and went with the cure 5/3. It has fully taped seams, and the velcro ankle straps do a great job of keeping the water out when you're kiting. And the Neoprene is SOOOOO nice.
I didn't have good luck with my Mystic wet suit and ended up selling it on ebay.
The problem I had was my height and large calves.
To tight and not an easy suit to get in and out of if your by yourself or even if
your with your buds. Pain in the ass. I also bought the waist harness which is
the nicest one I've ever had. The harness never moves and has great support.
I ended up with a Prolimit XL tall and that works for me. Don't buy anything
until you try it.
I've a new Mystic Cure 5/3DL brown (3sessions in it). I love my new wetsuit!! It's very stretchy and very very comfortable. Until now i'm always warm and the wetsuit it's almost 100% water-flush free (bad to piss in your wetsuit )
i can definately recommend the cure, ive had loads of different ones including a few mystic but this is far and beyond any for flexibility and comfort, the neoprene is just so soft and stretchy
its as warm as any but super comfy and thin no rubbing round the neck and very little seepage
