... yes agree with rattlehead,,, mostly,,, disagree on the bar but like a lot of things,,,, beauty is in the eye of the beholder. I much prefer the North bar but the Ozone is fine too. Interestingly, you can use either bar on the Dyno but you can not use the North bar on the Ozone kite and not because you can't but the Ozone Edge doesn't like the Y point high where as the Dyno is good with a high Y but fine (and some would argue finer points on this) with a low Y point.
The constrution build of both kites is as expected from well respected companies, good with just the right amount of re-enforcements where necessary without making it too flimsy and yet light.
A copule of examples of how strong they can be for even a light-ish construcion, I've watched my mate with his 19m and 13m Edge abuse the begeezus out of it and it still comes back for more, from not so eligent selflaunching on rough-ish beach, to kite loops and massively overpowered, all good, no damage or excessive wear or tear to show for it, so to me, they are fine.
Then, on the other side of the coin, another mate smashed his 2013 Dyno into not only the beach a few times but into the water, even getting rolled in the surf with kite going inside out as it relaunched. From being massively over powered too and mistakes in self launches or landings,,,,, luckily no damage, no fuss, all good also.
Sure they may have been lucky too but for so called lightly built kites, much tougher than you'd think. Secretly I was happy to see my mate dump his Dyno in the surf as I saw for my own eyes how much abuse it took and yet it was still fine so hopefully if I end up doing the same with my Dyno I will be fine too.
Both kites are very similar in lightness in the air, relatively light bar feel, quick turning speed and healthy power delivery when you have good apparent wind when speeding along but where the differences become a bit more obvious to me is the Dyno has a bit more bar feedback and instant drive when bar is pulled in than then the Edge. I found the Dyno suited lightwind surfboard riding better but once you have speed then they become similar again.
When I've riden the kites in surf, when you loose power in board on a little wave, maybe trying to catch one, single swoop and pull the bar in and the Dyno gets you going but I found the Edge needed a second dive or rise in the kite. The problem with that is you've lost the little wave your trying to catch or stay on. I think that with more time on the big edge I could dial it in better though. I actually had a ball on the 19m in Bali on waves and sure, it 'aint no Dice/Reo but with a bit of flying, it can do much more than you'd expect from and all being a "race" kite.
If direct bar feel is important to you then this is where the Dyno is better in my opinion, again not direct like say a C kite or Rebel, but as direct as you can get in a large bridled kite as you can get. Edge felt quite soft to me but it is also something you can get used to quickly too.
Either way, both kites are good kites and despite the so called light constution, stronger than you think, and the one area they really shine brilliantly is they are great light wind kites.
