Looks like the new Superflyer can be a great alternative for the Severne red wing. I tried the Fanatic Flow foil on the Severne Alien 155 and did not feel balanced. Other foils in the pictures are NP Flight FR 90, NP Glide Wind 1300 and GA freeride 1200. Foils are placed with fuselage mast inserts levelled.

Appreciate it. I wonder since the stock Starboard mast is raked at 87 degrees, if the other masts are also raked or straight at 90. Starboard says their 90 degree mast pushes the wing forward 5cm.

Have you tried any of these other foils?

It is interesting that more freeride foil wings like the SB Evolution 1300 are going to AFS style F series wing and in this case looks essentially like the AFS F1080 wing with the downward curved wing tips and relatively higher aspect, and stabilizer with tips also curved but upward, that style is probably not unique to AFS, just what I own so noticing it. The new Lokefoil 1100 wing is even more similar to the AFS F1080 wing in-terms of surface area.

Currently using the Redwing which is probably the most comfortable foil ever made . It is pretty fast for its size too.
The GA is okay but I did not like the narrow mast construction, too much flex, maybe if you are lighter rider it is not that bad.
Have not tried the NP Glide Wind foils yet, they are just not very popular maybe because they only come with 80cm mast and fuselage is pretty short compared to other brands.
I will try the Superflyer soon with carbon mast.

Based on my experience with the original Supercruiser and using the 1300 E-type which the new wing is based on I'd say it's only going to balance on boards with very compact geometry like the FoilX. It'll be amazing on those boards but limited to them.
If you wanted to run that front wing on a more typical board I'd look for one of the other Evolution fuselages, I'm shocked they don't offer that as a package option.
