Nice video comparison and location
I've owned the Chrono V1 V2 and Ultralight in size 15 and 18 and this video really demonstrates why the UL is the best.
I'm blown away by this kite and how little wind it takes to ride with it. I've been riding it with Zeeko Spitfire hydrofoil for a few days in 5-8 knots (I ride in the ocean often alone so this is my limit I'm pretty sure the kite can fly in less wind especially with a more skilled rider and larger board.)
1. It inflates instantly at the side of the window with no pre inflation it doesn't jelly fish or wingtip tuck ever.
2. It hangs in the air better than any foil or LEI that I've owned (including FS, OR, BRM, Naish)
3. The UL relaunches every time in these light winds (deep water) you rarely need to reverse it off the water just pull one line. I've had it tip wrap and invert on a blown foil jibe and I was sure I was done it sorted itself out with very little input from me .
4. Turning - this kite turns great for a 15M foil very responsive and fast no wing tip tucking. Very little delay in input flown on 55CM ozone race bar with 25M lines. I'm going to try it with 17M lines just to see if I like it.
This kite flies upwind like most good foil kites what surprised me was how solid it was going deep and fast down wind on the foil it just stayed where I put it.
If you want a no drama foil kite that works in sketchy light wind conditions and aren't out to win races give this kite a try.
