has anyone flown one of these, heard nothing but good reviews bout them?

yep i had a go of the 10m in 20+ knots one day, i was quite impressed actually. turned very fast, lots of grunt and quite stable, excellent windrange and lots of depower on tap for a C-shaped kite. looks to be well built and sure was lots of fun to fly.

from what i have heard is they are excellent high wind kites in the surf but have no low end power for those lighter days

they're meant to be like the naish helix or cult etc etc.

true cause i fly havocs now and i need a 9 for the 25 days not relly wnting to have 2 diff kites in quiver but all i keep hearing is how good they are

I sell Blade Kites and others, to answer you question i fully agree with the comments of
kiter zac an Neill.
I got a 12m on the market, like new, i used it a bit.. for my 85 kg i find it works best from 22 knots on, i can fly it up to 30 knts without useing the depower.
Its not for me for the lower end wind range..
Blade produce good quality Kites.A graet plus.
hope that helps,
