Thanks for all the replies. I have answered everyone below (i hope)
SupaEZ - looks like sharing a quiver with the wife is working out really well for you, thanks for your input.
dyyylan - I think you might be right and i should go for a 12m maybe, now i am really confused !! In a past life my quiver was normally 5 kites 6, 8, 12, 16, 20 but i am really trying to minimise my quiver due to cost, storage and cost, and cost

I dont usually ride unhooked as i try to protect my ankle (had surgery on my ankle, dont ask, but is was kite related), plus its never really been my thing. As i think i wrote previously i am old school (45 Years old now) i like rotations big air, board offs, dead man and all that
unfashionable stuff., also some smallish waves are fun also but i am by no means a wave rider.
RDM - I have not flown any kite for almost 5 years, prior to that i was running a Kite school in Egypt and rode mostly Raven as i liked them very much. Before that i was riding North Rhinos.
I am now in Austria (Vienna) I dont have any kite buddies here (yet) but i do have a contact that can get a good deal on North kites here. I have never paid retail in my life so this is really important for me. I was kite buggying for almost 10 years before getting on the water and always had trade options as a sponsored racer. These are all in the UK and now historical (probably) but time is also important as i go on holiday in 3 days and wanted to buy some kites to take with me
s29feb - My main venue will be on Neusiedler See (lake) in Austria with vacations to the sea 1-2 wks each year. The winds i expect are shown here
http://windalert.com/wind/spot/52697 I would normally head off to go kiting for anything between 13 and 30 kts and ride whatever it is when i get there + or -
I am currently
thinking that the 15m is my big kite
I will also need something i can ride in 25+ kts and i dont want to be hanging on for my life either so currently i am still thinking 10 or 11m, if i go for the 11m then maybe next year i could get a smaller 8m kite for the windier days. But then i am back to 3 kites ???
Thanks again for everyones posts and keep them coming please.
