I've got a 5 m2 Soul - my very best kite for hydrofoiling in waves
Got it this summer, brand new
Just teasing as I believe you are talking about the Flysurfer Soul, and not the Takoon Soul from 2011
It is the perfect kite for surf foiling though, as it is higher AR than newer LEI kites, and loads of depower and range.
It was also the best wave kite for surfboards too
The higher AR on small kites is great, as you got so much more peak power which is essential quite often, in waves.
Can ride with this 5 m2 in 13-14 knots with a surf wing, being average weight, works excellent!
Off topic though, I know - just funny as I believe it is quite rare that anyone reuses kitenames from other brands
