Well, don't worry about the Peak sizes.
The Peak 6m has got the power of a normal 10m foil.
And the Peak 9m is about a 14m foil power.
This is what written on the brochure and we can trust it as the designers are really experienced.
My feeling is that the Peak 6m is closer to be a 9m foil and the Peak 9m closer to a 12m but I only tried them for one session and it's not enough to be sure.
So, at the end, Peak 6m and 9m are definitely OK for any snowkiting conditions.
When Peak 6m will be too large for the strong wind that will be time to give up as it will be too much dangerous conditions. And when the 9m won't pull you, be sure that nobody around will go cruising, that will be less than 2 knots.
My feeling with the Peak is pretty good.
This kite is really light weight, super easy and fast to launch and land by our own, very stable.
It's always difficult to speak about our feed-back for a kite as it's been so much different opinion from a kiter to another one all the time and about all the kites.
Anyway, the product is really well made and is reaching the aim for a super light weight kite and minimal size packing, perfect for expeditions, high-mountain cruising and climbing, trips with flight airplane, teaching with safety in low winds range, the performance is very similar to all the kites on the market.
Don't hesitate to meet a Flysurfer Peak Test-Day around to get your own opinion, PEAK worth it for sure.
My video on snow about it is ready, we're waiting for the Flysurfer headquarters' green light.
So, stay tuned, I will post the link as soon as possible.
