My post from before is too old to put replies on anymore so will continue the saga here... Several of the tassie crew now have drysuits, keep tuned for how they're going. And before anyone from vic fires up about concrete, a heap of kiters were seen over there last week using drysuits while we've all been charging in 4/3's here...

Great replies from the previous thread, we've gone ahead with the Ocean Rodeo Pyro drysuits with a mix of Pro's and Surf's. Mine is a Pyro Surf so i will describe that one.
First impression is that you are wearing a huge chip packet - that thing crinkles when you move! Took about forever to get it on the first time, taking care with the gaskets and stretching it over feet/hands/head as recommended. Had some bunching of the inner liner up below my knee that needed sorting out, but the internal bracing system seemed simple enough to sort out. Got pretty hot standing inside wearing it with the OR fleece inner, was worried about sweating heaps inside while on the water.
To explain, the thing has a waterproof loose inner membrane that the gaskets attach to, and a lycra/neoprene outer that sucks it all in to decrease the air volume inside.
Put the neck gasket on and my eyes bugged out of my head - a couple nights with the neck stretched over a medium pot loosened it up a bit, but it still feels like a tight and uncomfortable fit.
Second time getting the suit on was much faster, about the same speed as putting 3 layers of wetsuit on, maybe a tad faster. Conditions on the day were about 6 degrees, no wind and a whole afternoon of being towed behind a boat on a surfboard in about 11-12deg water. Outcome = dryzabone and warm as toast while the other blokes were shivering in the boat haha! Rotating turns means you sit in the wind while the boat is moving, getting cold (usually) and waiting for your go again. Took more than a couple hard and heavy smackdowns trying big wakestyle jumps, landing headfirst, arm first and feet first, and not a drop of water got past the seals. Am very impressed with this suit!
Another bonus was getting changed at the ramp, peeling the suit off and finding the inner fleece was stil dry and hardly any condensation inside. The next day the other blokes were pretty sore in the back from being towed about but apart from a very slight bit of stiffness i was fine - usually i'd be locked up with some kind of back spasm. I put this down to usually your cold in the boat in a wetsuit, and then out hanging on tightly to the tow rope - with the drysuit i put this down to being that much warmer and not having a cooling down effect. While riding i didn't notice the neck being tight (but not restrictive) and did not have an issue with sweat condensation either and was skurfing for about 2-3hrs.
Will pump up a shorter review after the next kite session and some pics etc as there hasn't been any decent wind on since the suit arrived.

**UPDATE**
the gear works SWEET on a kite.
15-25knots (gusty) in 3ft waves, onshore
allowed the harness to spin freely slightly to the side when switching to toeside, felt comfortable throughout the whole session (4hrs+). Very easy range of movement, took a couple hard smackdowns and crunching by waves.
Stopped once for a bit to have a yarn and a piddle (super easy, just unzip, take one arm out and pull down to waist - pee hole in undergarment worked a treat was toasty as the whole time). Will leave it on next time when going home in the car cos I got cold waiting for the heater to come on in just my jeans and hoodie.
