The first slingshot infinity 99 wing video was quite popular but it never really answered questions for foilers looking
to get into real light wind foiling.
We tried to address everything we could think of (but I'm sure we have missed something lol) so there is a little bit
of everything. Its a long video so we added chapters if you want to skip ahead and get to the technical stuff.
This footage was from yesterday, it was a particulary gusty North to North East wind with a range of 5-15 knots, and the i99 light wind capabiity is truly staggering!
By the way the green washing up glove is nothing to do with Covid-19, it was from a dog bite and after the swelling went down, I had to keep the cuts from getting lake baceria in it (which I have expereinced before and its no joke)

Thanks for the video and info about the i99.
I would be interested to know what other large foils you've tested for comparison purposes -- Armstrong 2400, Moses 1100, etc., and how they compare to the i99 in light winds (early lift, top speed, transitions, stall speed, etc.).

Unfortunately there is no financial way to test every foil combination out there.
The two brands you mention I have never seen wind foiled in our parts. Armstrong looks amazing for SUP foil and wing dinging but little info for low wind, wind foiling,
Over the years we have tested what ever is available (meaning what as a collective group we have bought) Naish, NP/F4, Horue, LP, Slingshot and Fanatic etc.

Awesome video Dean, thanks - you're the freeride light wind guru for sure

Wish we had your guys wind, I do love the strong stuff 
However all the years windsurfing, I could never use the small kit unless it was nuking so it does feel pretty amazing to fly in next to no wind and be out on the water frothing
Like the close up video shots of the board hovering over the water. Got the next 3 days off. Wonder what those 3 days will entail???? Aww, foiling, foiling and more foiling!
CoreAS thank you for the comprehensive review!
I recently bought one of these wings.
Wow!
So easy to pump onto the foil even with my mediocre skills.
Super light wind foiling is now a possibility.
Keen to try with a wing thing too.
Dean, thanks for a fantastic review of the 99. You covered it all so completely, from setup to wind speeds and action on the water. Knowing your weight helps, too. Now I've got to have one. I just made the move up (or should I say down) from a Dialer 145 to a Wizard 125. It's really great to see you on my board and talk about setup. Out for the first time on the Wizard this week with a 6.2 and i76 wing in 10 mph. I'm 185 lbs/84kilos. Nowhere near enough wind for that setup and my skill level. Not even close to a takeoff. Looking forward to better skills and someday soon perhaps that new 99!

Sounds like you're loving it as well! I use the i99 for wing dinging as well so 2 different sports with the same wing is a win-win :)

You're welcome Marc5, glad you enjoyed the video and that helps with set up questions etc.
The Wizard is just magical for marginal wind area's (even up to 30 knots)
Thank you for the feedback, much appreciated :)
Is it worth it, to also buy the Infinity 99cm wing, if already having the 84cm version?
Aka, can the 99cm maintain flight at a much lower knots board speed versus the 84cm version?

Yes absolutely worth it.
In the video, section one is the stall speed, it's difficult to tell but I'm foiling in 5-10 knots at times, no way the i84 can keep that going that long. The amount of energy stored under the i99 is staggering.

Seems like the 99 is a more logical jump up from the 76 compared to the 84?
Yes, if the 76 is your main wing. The overlap between the 84 and the 76 has always been pretty large.
At my weight foiling in very gusty inland area's here is my wind spread per infinity wing.
(Its quicker to change out a front wing then re-rig a sail so having multiple front wings gives you the ability to dial in)
i99 - 5-15 knots
i84 - 10-20 knots
i76 - 15-25 knots
(I then use the Time code for 25+)
Another data point. My weight is 92 km. With a 6.8 sail I can fly the i76 from 10 kts (with a lot of pumping for takeoff) to 17 kts.
The point is that the i76 has quite a lot speed range. It also has a wide (fore and aft) center of lift balance range. It also has a nice mushy stall.
If I owned only one foil, this i76 would be it. My quiver in Florida is the i76 and nothing else. It covers pretty much all normal wind conditions in Florida. The issue with Florida is finding deep enough water inshore.
I know a couple foilers in the Columbia Gorge who own only the i76 and nothing else. They foil it with sail sizes 3.7 to 6.7 .
(My quiver in the Columbia Gorge, where I live, is AFS, LP, and Moses. We snowbird a couple times every winter to Florida, but we are still stuck in Florida from the covid until it gets safe enough to go back home. Could take a while. We have our own house and van, so it's not terrible.)

Its really interesting, we all have such different experiences on each wing.
Many variables to contend with!
Fresh water versus saltwater, inland winds versus coastal winds, tide, currents, ground swell, voodoo chop, board type, sail size...you have rider height and weight!
Then you have foil set ups, fuse positions, mast base pressure, boom height, harness line length and foot strap locations...Basically what works for one will feel totally foreign to another

So with segler saying: "Another data point. My weight is 92 km. With a 6.8 sail I can fly the i76 from 10 kts",
then what can I expect, as my weight is 70kg, with a 6.0 m2 sail and the i84cm wing?
I can still go flying at below 10knots speed?
Or are you saying that I should have bought the i99 now to be fully comfy and airborne at low board speed?
Cyber - at 70kg I think you'll struggle to fly over ANY wing for about a day and a half, and after that brief struggle, given decent pumping skills, you'll be able to fly any wing in 10 or so, and may even wish you had the 76. The 99 is for 100kg hate-to-pump slugs like me, and I wish I had one. I have the 84 and need a gust around 14 to get up although after that I can stay up in less. For you it'd be unnecessary just as soon as you had half a sense of what it takes to foil at all.
I am a newbie and sail without footstraps on a SS Dialer 130L board with a 6.8 sail and I'm 175 pounds on the i84. With 10 sessions under my belt I'm in flight most of my sessions now. I have been in a variety of different wind strengths and now realise I need a minimum of 10-11 mph of wind to get me up on foil with the 6.8 sail and can sail in 8 mph lulls and I seem to max out being over powered at around 15 mph winds. Then I need a smaller sail. Still a lot to learn, but I have grasped a lot so far.
