Hey there Frothers,
The new SABFoil range is amazing and I too was a little surprised they dropped the W1110, it's a great wing and was a better option for me and my downwinding than the previously used W1000.
The W1110, W1000, W800 and W740 were all part of the same family and were originally Windfoil race wings which then were adopted by surfers including Kai Lenny who rode the W800.
As speed/race wings they had clearly defined stall speeds and great top speed and glide so long as they were riding fairly quick.. The Anhedral shaping and this profiles lent themselves to really great upwind performance also. They worked well for lightweight surfers for wave and pump, but people's needs have changed as the sport has developed and there is more emphasis now on low speed glide, pump and speed for downwinding and flat water pump.
I've been riding the W1150-L Leviathan all summer since it's release and have had a mad love affair with this wing. Although touted as a pump wing (which it's insane at), I have employed it for downwind and pumping whilst downwinding. Coming from the W1110 (and previously the W1100 and W1000), it was a learning experience, the Levi has an extremely low stall speed, hard to get your head around a wing that I practically refuses to stall at walking speed. It has amazing lift which doesn't increase with speed and translates into more energy extracted from every turn, drop and bump you can find. It's super fast, more than fast enough for any speeds you are likely to encounter whilst downwinding in any conditions. It's glide is simply insane and slippery profile makes it an almost flawless downwind wing.
The newest wings to the fold are the Razor lineup. The Razor runs on the same fuse, T6 bolts as the W1110/W1000 etc and is a fusion of design between the Blade and Leviathan ranges. It's low surface area, but thicker profile added to a very high aspect shape gives it an amazing fusion of speed, mad glide, soft stall, aggressive maneuverability and easy take off.
The Razors have introduced the new standard for wing foiling performance, less technical and faster than the Leviathan, they add the one thing the Levi's didn't really offer, and that's radical and aggressive turning and carving. The Razors have all the qualities that the Blade range have that are appropriate for wingfoiling. The Blade range still are more suitable for windfoiling and racing as their anhedral shape and thin profile will be ultimately faster but at the cost of user friendliness.
All four wings are still absolutely amazing in their own right but if you select the right wing for your chosen discipline, you'll likely enjoy the same love affair I've had with the 1150-L and now all over again with the W980. The Leviathan W1150-L is now my go-to wing for light to moderate wind downwinding (12-25 knots) and the W980 Razor is my go-to for moderate to strong downwind sessions (18-30 knots).
The Razors are available in W980, W880, W820 and W780. I hope this clears things up a bit. After riding them, it's very clear where they all fit. We have all these wings (and many others) available for demo from our store.
@Poimax05, For light wind wing foiling, I strongly recommend trying the W980 if you have the T6 kite Fuse or the Leviathan if you have the Surf Fuse. As an aside, the Surf fuse now comes in a 663 length of better turning and more sensitive pitch.

PS. It's really hard to show the curves on these wings so please excuse the lower pics. I did my best. All stats and profile info on the SABFoil website.

w1110 and W1150-L are quite flat whereas the W1000 and W980 have anhedral curve.

All but Levi have very high AR. Shows difference in surface areas. Levi is king!

Tried to show the thickness of profiles and leading edge shape. W1110 and W1000 are sharpish leading edges with fine entry angles, this gives less drag but more pronounced stall features.

This pic shows the thickness of the profiles and where the thickest section is. More forward than the W1110 and W1000. Makes stall softer and slower. All four wings are very quick and none rise with speed unlike many other brands.
