Have you noticed that EvoX ,Speedster and RS-flight have head extends above top of mast, so looks more like "pointed" sail?
This feature is well know in aerodynamics,reduce wingtip vortices,reduce overall drag and make sail/wing more efficient.
Long time ago there was NP Z1 with this aerodynamic trick:

My old Evo X used the same design concept :)
^^^^ That will be faster, lighter, more range and only work on their sail due to spectechflex laminate from the Roswell files
