Got out today on the zephyr in the pond (Westoz), Won't double up on everything else that was said.
Started around 10 to 12 knots on my mako king only on a 50cm bar which I hadn't adjusted the knot under the floats. Still able to stay upwind easily enough, but lacked punch. Changed to shortest knot and different experience altogether.
First thought was this zephyr sits somewhere between the New 2013 Catalyst and the edge. Developed more apparent wind than the cat, but less than the edge. Very smooth, very consistent, very stable, very ozone!
To make this clearer, there wasn't enough to warrant any kind of jump, and yet (those who know the pond) one tack out to the weed bank and back I was hitting the shoulder of the point and having to bear downwind to get back inside the pond. This is testimony to the apparent wind build up and the edge DNA built into this kite.
Wind picked up to 12 to 13/14 and now I was nicely powered. Started to throw down a few of my gay ass style hooked in stuff. Forward roll transitions with a forward loop. Back roll with back loop transitions, some one foot board offs..I know I know I'm an old school tragic!

Nice floaty jumps and plenty of time in the air to adjust accordingly, but was a little slow on the loop.
Changed to a bigger bar ( the one it comes with) and the loops were noticeably easier to execute as you would expect.
While I didn't do any unhook ( too old, to gay and not good enough for that) tricks it is easy to see why the promotion video shows this. This is a very stable canopy and not unlike the new C4 you can feel where the kite is through out the loop.
Got on an axis vanguard TT (nice board hey, wish I had got on the smaller carbon board but got the call for the war office and has to go) which has excellent pop, and the back roll back loops were as easy as they are on a much smaller kite. The kite would drag you through the rotation just right.
A fella who has a quiver of edges and catalysts also demoed this kite and when I left him to it was relatively convinced that when he got his new 19m edge ( he weighs a fair bit more than me, must be near 90kg?) was convinced he would be changing his 17m edge over to the zephyr. When I left is was blowing probably 15 to 18 ? Plenty of whitecaps and he was still very comfortable.
It seems they have designed a much better bottom end in this kite and yet maintained that top end zephyr riders have always enjoyed.
So it seem this kite has enough apparent wind edge like built into it to respond to an efficient board ( didn't test this but easily predicted on what I experienced) and yet will still afford a degree of freeride and freestyle.
Guys they have done a good job with this kite hey. Worth a demo for sure.
Would I buy one at 75kg, yes, if my marriage wasn't important to me and I didn't have a 14m cat on order ( present from the wife for my 40th).
Don't know how many retailers have a demo on offer but I just cracked a brand new zephyr which is available across from the pond at Westoz. Love to hear your thoughts after you've ridden it.
Ps some clarification on the wind, it was not driven much by a thermal Seabreeze. Maybe driven more by the weather coming. For example tried to go out down Mandurah on a 10m edge on a skim board 4knots lighter and couldn't stay upwind even though there was some whitecapping. In short wind was gutless today.
Pss further thoughts, I have a gut feeling that ozone may one day make smaller size zephyrs, as an almost free ride edge. So REO, cat, free ride edge (zephyr) and an edge. I think the zephyr in smaller sizes would just slow the kite across the window enough to make an awesome free ride kite.
