I just wanted to report back after starting this thread about my kite selection dilema.
I have now flown the 11m Rebel and 15m Dyno. The Dyno was not really in suitable conditions to form an opinion yet but the 11m rebel was very nice and flew very well indeed. I cant quote wind speeds as i have no idea what it was blowing, all i know is there were + 10 kites on the water and i was the only person riding and staying upwind on my Nobile 666 (126 x 38). Nearly everyone else was on much bigger boards and even direction wave boards with kites ranging from 11 - 14 m in the air
Its a long time since i was on the water previous to this and i spent the majority of my 2 hr session just riding up and down (I was very nicely powered) so i could settle back into riding slowly. In my absence from the water (2007) i have undergone several operations on my foot and one also in my ear ?? so i did not want to push it too hard to start with plus i am very rusty and looking to regain my confidence on the water which was never a problem before now. I sent the kite a few times and was more than happy with the lift and speed of the jumps and landings and am really pleased that i opted for the rebel. Obviously i still have nothing current to compare them too but never the less i am yet to find something i dont like. I have not tried to relaunch yet as i don't normally drop them and with a 5th line this is straight forward anyway. The very short run i had on the Dyno was in light wind (of course) to which i would normally be riding if it were not for the 2m waves crashing onto the beach in onshore wind which made it impossible for me to get out far enough to start enjoying it but it also handled very well, turned nice and fast and looks like it will be a nice addition to my new quiver. I was also impressed with the North bar. it was easy to adjust for my preferred reach , feels much more comfortable than the last NKB bar i tried in 2007. Also the lines are really nice and everything else just works in a way you would expect from one of the leading kite companies.
I will try and write again when i have more experience with the wind range of these 2 kites and the overlap i have (or have not) when switching from one to the other.
I am currently on vacation on the Black Sea, Bulgaria http://lozenets-blacksea.com/e2/index.php/site/cameras/surf-condition
it is not a real kiteboarding vacation as such (not the windiest time to visit). I am here primarily to spend some time with my lovely wife and 1 year old dog (Chocolate Labrador - Kai) who loves the sea by the way.
Anyway thanks again to everyone for all your comments and advice, hopefully i can also pass some of my experience on to some others in a similar situation as i gain more time on the water with these kites.
Tight lines to you all,
