@ Onda, give an Ozone 10m V4 a testride...you will be amazed how it feels / flies against the V3!
I had V3 in 12/9/7/5 and changed them last year into V4....Now I am very happy, I did not like the V3 i many ways...the V4 is a dream to me, smooth, stable even in gusting wind, where the V3 had a way to jellyfish its tips a bit the V4 does not move, it absorbes the gusting winds, it tunrs so well you can do anything you like without getting punished.
It hangs in the air when others are just falling down.
In its lowend, just give it like max 3 sining strokes and your gone.
I will not buy the new V5 which is coming soon now, as I am totally happy with what I have , but I will test it as soon as it is here, but it will have to be a whole lot better ( how?) for me to get rid of my V4.
Btw I have 82kg, I ad 3m extensions to the 12m V4 so totalling in 28m use an Airush sector V5 54 and am mowing the lawn together with the guys on their big flysurfers... the lowend of the 12 goes up quite a bit...on 25 m it is also a kite with a big high end.
The 5 m I fly with 23m which seems to be the perfect match for me, I tried it on 20m it stays too far back getting pretty direct...on 25 m it flies to far forward if you let it, 23M meter on a 45cm bar seems to do the job.
( I only use directional boards)
