2 cents from someone who spends a lot of time flying inland New England conditions.
First, we have to be clear here, SIZING IN REGARDS TO LEIs AND FOILS IS AN APPLES TO ORANGES COMPARISON. If you were to take a 7m Frenzy out in
conditions you take your 7m Wainman out in, you're going to get your backside handed to you.
What matters isn't the flat area of the kite, it's the projected area. In other words, the amount of the kite that is actually doing work. That
wainman is a great kite in nukin' conditions because you are on the water and it's projected area is probably around 4m. In your weight range, a
consummate high wind kite.
That 7m Frenzy has a projected of almost 7m so it will be considerably stronger. Also, you have less resistance on snow/ice (think similar to foil
boarding) so that is a factor. Given that you have a "7m", this means it's an older Frenzy and as such gruntier and less depowerable than any of the
recent versions. So if researching wind ranges for that kite (which I suggest you do) look for somewhere pre-2013. Most wind ranges are based on
160# so there is some fudge factoring to be had but they offer a good baseline.
The 7m Frenzy, especially in the 04-06 versions, is a beast and for many in the early days was very close to a 1 kite quiver on snow. IT WILL NOT COME
CLOSE TO THE HIGH END OF YOUR 7M WAINMAN. Conversely, that little Wainman isn't going to come close to the low end of the Frenzy.
I guess my question at this point is which version of the Frenzy are you getting. If it's any of the Y line versions, do yourself a favor a convert
it to 4 or 5th line.
At 180 pounds, and I'm guessing you're on a board, a 9m would be a better option.
Also in the winter, you need to take into account temperature induced boost that you encounter with colder denser airmass in winter. Your Best TS 12m
in 15 knots, warm weather on water is considerably less powerful than it would be in 15 knots at 20f on snow. We often see water riders make this
mistake.
12m Unity wind range in standard material is about 10-18 kts. The Frenzy is going likely going to start where the Unity leaves off and get you up to
about 28kts+ depending on your skill level both in the flying aspect but also in what you do with your feet. :D
2 kites to make up that range for part-time snowkiters is pretty common. I wouldn't rush out to get a new foil unless you really want/need one. And
then if that's the case, there are a lot of really good options out there beyond the Speed 4.
Consider this also. Not all kites are equal and kite design matters. For example: In 12kts my smarter half can ride the 18m Ozone Chrono UL. She's
5'9" 130lbs. In the same conditions, I can ride the Ozone R1 in a 10m. I'm 200 lbs. We will be fairly evenly matched in power, I will have an upwind
advantage, she has better hucking. Modern kites have a broad spectrum of performance these days.
This being the case, B-Roc's position on the 10m Speed 4 is spot on. That Speed is going to do essentially what your Unity does. But it will be less
forgiving, more fun on the upwind and a much better huck machine. So you have to decide do you want ease of use and high safety factor or something a
bit more sporty?
And I agree with Abkayak. Though my 9m Closed cell kite of choice would be an Ozone Chrono V2. They have been more reliable in the gusty stuff we
fly in compared to the Matrixx, have better depower and better upwind. Add a set of line extensions and you can get nearly 12m performance out of it
as well.
Now that the V3 is available, the V2 can be had for fairly short $ compared to what they were. I've been holding off on selling our 9m demo just
because she's just too darn nice to fly. :P
