I'm very happy parawinging my F one Eagle x 900; good low end, good glide, surprisingly good carving. Considering how big a difference it made going from the 16mm mast to 14 mm HM, I'd be very curious to try F4 foils and would seriously consider them if I were buying into a new brand. They have a mast that's supposed to be 11.3mm thick with 100mm chord. Walt was crazy excited about riding it with their DW 12 AR foil Orca on X foils podcast episode #44. Buy it and let us know!

Otherwise AFS with Enduro foils seem very nice!
