Hi Dapole,
The 2003 Airush Lift Pro 11.5m was years ahead of it's time. Designed by Ben Severne as the epitome of performance, it was a lethal weapon in the hands of anyone unprepared for it's power and speed.
It was a true "C", in other words, it was a ba$tard to relaunch, luffed if not careful and had little depower apart from edging really hard. Of the old time kites I had a few really nice fave C's, but the Lift Pro was AWESOME! I think it was head and shoulders above the X4 and the Rhino. Rhino was powerful but pulled too far downwind and X4 well????
I had a few jumps back in 03 that were as high as anything I've done on the best boosting modern kites. Testimony to a sweet design. It had a wind range of 15 to 30 knots which doesn't sound like much but back in the time, a 10 knot wind range was pretty good and most had three kite quivers to cover the range you can do easily with 2 modern kites.
Each had their faves I guess but the Lift Pro was special and damaged many people who tried to handle it......hey VB Man.

I loved it and would love a nostalgia ride if I ever came across one again.
Cheers,
KH
