I didn't have a chance to try the Sultan Wing but I have the Carver 5'10" 85L.
Yesterday I rode the Carver with North HA1050 and swapped the board on the water with 2 of my friends who want to try my board. They rode 1st gen AFS Blackbirds one with 6'2" 90L Blackbird + AFS Silk 850 and another with 6'4" 110L Blackbird with AFS Pure HA1100
Both blackbirds are wider than my Carver and much more stable and much easier on the rough sea. One of my friends can't foil on my Carver at all in 15 minutes. The condition is rough with messy wind chops + cross swell.
The Carver is a faster board on the water they both agreed.
