... oh boy does the Zepher have some top end

. The Ozone/Underground guys were in Vietnam while we were there and we watched one of them on the Zepher while alot of others were on 10's, he hung on and did some of the biggest, floatiest jumps!!! I would say, even with my super heavy weight, I could not have held down the Core in the same wind! But then again, that's not what its for.
My mate with his Zepher can hold it down in winds when I'm having lots of fun on my 14, but if the wind drops he can keep going while I start walking, but again, being lit with a big kite is not as fun as being lit on a medium kite.
Like I said previously, when you pull out a 17m your aiming for a light wind day session and usually on some sort of directional or race board. Infact, in 10 to 12 knots on a race board and the Core, it feels like your lit in 20 knots which is fun, but as soon as you stop driving off the fins you realize its actually light. Again, the m.o. of the 17m is light winds.
Personally, the Core has a waaaaay better bar, horses for courses!
cheers,
