Yes it is a sonic² 9 m². If I use the big 1000 cm² Cruizer wing then I (63 kg) am pretty much the first on the water, just maybe semiprofessional race kiter out, but then just with biggest kites to compensate their extra drag
. I never use my 11 m² sonic race in combination with the big 1000 cm² in the lowest winds as the risk to ride into a lull is just to high, I have the 11 m² just for boosting around 10 knts, see viewtopic.php?f=196&t=2393935&start=113
And I for sure often have been out in more than 20 knts in longer gusts with the 9 m². It is my kite to boost then with the 680 cm² Element (or 580 cm² Aspect) wing or using its wide windrange to go distance, where windforce can change a lot, see: viewtopic.php?f=196&t=2393935&start=234
A freerace kite as the sonic is also very helpfull if you want to do manouvers as it holds you up especially during tacks and so even small 580 cm² wings become usable as mono, but to me for sure just with straps.
I also want to try strapless again since a while but didn't made it yet, but anyway not so sure if it will fit my demands and here I think you have to ask Øyvind.
So for riding straps and if, as I would expect, you are well in doing flying tacks (in the best case with full strap to strap switch) I would recommend to first try to learn flying tacks as there is just a very small difference between mono and normal foil. Not to say if you get used to it I would even say mono tacks can feel easier and safer as if you miss some power on the end of the tack it is more easy to turn the mono the last 90° on a dime and restart more downwind in the direction the kite pulls you, while the stabifoil will prescribe the way of the turn much more. For sure as said a racefoil kite that lifts well and floats you upwind for a long time will be very helpfull.
Talking about jibes
with straps also a well lifting kite makes things easier but I also start to learn it down to the 2,5 m² firefly. But here is a big difference to stabifoils:
Before foot switch it can help to turn into a upwind course to have more pressure and so stability from the kite.
Directly before you switch foot in front of the jibe you have to bring:
1. the foil shortly into an significant ascending position (as you can't ascend unlimited here timing is very short)
2. in the moment you come forward with your old backfoot you have to hold up the nose with the old front food in the strap, which can mean to pull up your old front leg.
When you have both foot in both front straps you try to keep your weight completely in the kite as it is not possible to load the nose without diving it and try to bring the new back foot as fast back (in front of the backstrap) as possible.
The more floatier and bigger the kite is, obviously the longer time you have.
One big drawback of the jibe is that even when you made it till here, you sill have to place the backfoot into the backstrap (if you have one), which means flying the kite up again and powering up and trying to move back foot, which can also work by turning it around the heel into the strap, but anyway will take a bit of time and is a secound moment of instability. With my Wave singleskin kites I have to do jibes as tacks are hard to impossible with them, here I normaly profit from riding big 1000 cm² wing. But with my sonics and small wings 95% of my turns are tacks as so much easier.
Tried to find some good visible jibes but perspectiv is never perfect, sorry
Have to slow play the videos to see anything. Hope it helps anyway.
