Rad spot! Looks fun as ... for any kind of board!
Seems like they are all facing challenge on staying in the pocket, allowing any downwind direction means getting pulled too quickly along the face. So on a foil, I'd think the challenge would be more about being able to slow down enough to stay on the wave and ride it versus shooting out ahead of it too quick. Maybe aiming for a top to bottom surfing style would work better: top turn down the face, then cutback where you are pretty much going back upwind, repeat. Kinda like how tight S-turns helps control speed when snowboarding, versus longer drawn out GS turns ... aim for tighter turns almost like doing a series of figure 8s in and out of the pocket?
But easy for all us keyboard fliers to say! I know how challenging it is to drop in on waves a quarter this size and just deal with the acceleration in a straight line, much less stomping tight turns at speed. And then attempting to link the turns without pause adds even more complexity and commitment. It would help to ride it myself, to get a feel for it -- hope to see you there in 2025 or so.
It would also help to see video of you foiling it, to get a sense of what you're doing and what might be improved -- but that's the same for 99% of us, not going to happen, because the likelihood of anyone filming us doing this nonsense is virtually zero. D'oh!
Anyways, for wings ... I don't think you want a big surf front wing ... it won't be able to handle the acceleration in those waves. You need something that can go pretty fast, very quick turning / carvey, but also have enough surface area to handle the "pauses" in between turns. I don't have tons of experience with different wings, but personally I am fan of the stringy wings .. the new XL ones I think will be good for smaller wave carving, I bet the regular ones would work well for you. Similarly, I suspect the spitfire XLW would be awesome, once used to the rear foot bias (also helps for stomping those turns). Nice thing is ... both are just a piece of G10 sanded to wing shape, so with $100 in materials and a few hours with a belt sander, you could start experimenting.
