I don't think that FS will do Peak5 for foiling officialy, in such case all will buy massively cheap Peaks and no looks at Soul2. As Soul2 much more expensive they definitely make it possitioning as foil kite to make more profits. Even as with smaller peak you get more speed than with Double sking foil. Or... They will rise Peak5 prices and add foiling word
its nothing personal just buisness
And they will do with Sonic3, vmg, sonic races series if they also devoted to foiling too, to much overlaping happening in between.
Hard and serious working companies sometimes releasing products which they wasn't officialy possitioned for such better using propuses:) For example FS suddent success with Peak4 for foiling, Sonic series planned only for race but ended for all kiting cases, and best for jumps
Moses with surf wing Onda which is much better for kiting and got super top wing all around
