Today I did back to back test of FRS 9m and my 2+ year old, and 250 hours used ozone hyperlink v1 ul 9m on same bar with 20m lines.
I'm 76kg on gong m pro. Wearing 6mm wetsuit and gear probably 80kg.
Wind was solid 6-8 ms with some short holes to 4-5ms.
I was out over an hour on the FRS.
FRS is a great kite. No question about it.
Compared to my ozone:
Slightly faster turning initiation. Faster down loops.
A bit less low end I think, but hard to tell. Kite has less projected area I think, looks that way from the bar.
Same drift, stability, inflation at launch.
Holds air better. My ozone laying on beach deflates in 5 min. FRS still more than 50% inflated.( FRS I tested has 10 hours on it).
The guy who owns the FRS used my kite and had same conclusions. He felt my ozone was less stable on tips, but admitted its probably his unfamiliarity.
If you are looking to transition over to foil kite for freeride HF, this is an economical alternative, really I think you'll be happy. You can get a quiver 6-9-12 UL for 50% of cost of Ozone.
I've been overwhelmingly happy with my ozone hyperlink HLs., best kites I've ever owned for whatever I was doing with those other lei kites on TT, Surfboards and HF. The 9m has been used 85%of my sessions and flys like new without any adjustments. But the cloth is getting worn, and it's now at middle age. So looking at replacing it, was thinking about the FRS.
Considering how much I use this size, I'll probably get a HL v2 9m to replace it, really want that little bit of extra low end.
But if I was getting a whole quiver, the FRS would be hard to resist.
Edit: checked the published data:
PA of frs is 7,12 and ozone 6,98...
2 more cells on ozone. Otherwise identical.
Really wonder now about that low end, could be wrong about that.
