To be fair, I would not recommend the small 75l 17" Sultan Wing as a low wind specialist. Yes, it takes off more quickly than my equal volume Armstrong FG due presumably to the narrow plan shape, but if you're focused on a board that will reliably lower your wind threshold I'd go with a larger size Sultan wing - 85 liters is 18" wide and 5'10, or even the 95. I absolutely love my 75l sultan wing, but primarily because it disappears under me like a much smaller true sinker board and because i can prone it easily. It is an absolute pleasure to ride - though the 5'10 must be very very close. To reliably obtain the benefits of the DW boardshape, pick a volume closer to 95l and 18-19.5 wide, like the Armstrong 85/96l downwind boards. I have the 96l and even at 6'8" it feels much shorter and nimbler than you'd expect.
I'm relieved to read this. You echo my conclusion after using a Sultan Wing for the last month.
I'm on the Amos 85L Sultan Wing (5'10' long, 18' wide). I weigh 84 kg. I am a competent winger. I used a 60L Amos Nitro Wing (5' long and 24" wide) last season, and the one before that, a 90 L Amos Tomahawk (5'2" long and 26" wide). My biggest wing is a 5.3 Armie XPS; my daily driver foil is the MA1000.
I was disappointed with the board during my first session - I had high expectations. It quickly became apparent that this particular board would not be a proper light wind board for me. Therefore, I agree with your suggestion of 10 - 20 L over body weight for a proper light wind board. Subsequent sessions have been very different positive experiences in other conditions - everything from 10 to 30 knots. Calm ocean to big rolling ocean swell. Waves to flat and everything in between. But mainly on the windier side, a 3 m2 wing would have been the most commonly used size this time. And now I can say that this board is a quiver killer for me. I.e. the only board I use and can see myself using for this season.
The reasons for this are numerous. It allows me to ride my existing quiver and preferred small foils in much lighter wind than my 60 L Nitro. But not in crazy 7-10 knot conditions (that would require a larger wing, foil or board, IMHO). It pumps well (maybe even better than my Nitro - even though this does not make sense). It disappears when you ride, as you said. The width is not an issue once up. It's excellent in waves and open ocean swell. It already starts moving and accelerating from an early stage during a rodeo-style stinkbug start. This is a *huge* advantage over my Nitro and one of the main reasons it's a quiver killer. If you can point your nose downwind, this early movement translates to a "running start" effect. This, of course, translates to being able to use foils with a high stall speed. Combining these two effects is the most significant advantage of the board's design, IMHO.
Drawbacks: it can be pretty tricky in shore dump compared to a shorter sinker. It is hard to manoeuvre through the break given the shape, whether on the back (my preferred option) or on the side). It requires a rodeo-style stinkbug variation to get going (not a problem if you care flexible). It takes a while to learn to ride it. And to Lee's point, getting going in unruly conditions is *definitely* harder. I am getting better at this but not quite there yet. But it also took me a couple of weeks to build up the confidence and experience when I moved from a 90 L to a 60 L board. I can do our local downwind run with the board in 20-knot conditions but not yet in 30-knot situations. For example, I bailed on the DW run last Saturday because it took me 10 minutes to get up in those seas.
