I’m around 95kg and on my way back to 88kg. (14stone) and ride a Skimboard 54”x 20” (non-kite specific) having always used Twin Tips.
No fins or straps and kitesurf in shallow water and very much into flat water, small waves and cruising around ETC.
Looking at the technical data of the SOUL,
https://flysurfer.com/project/soul/ the AR ranges from 5.0 to 6.0 across the range (Presumably 5.0 equates to being Mid AR) with the PA of the 8m SOUL being 6.65m (83% of 8m)
The HL is a Mid AR foil, but unable to establish how the HL compares in terms of PA to the 8m SOUL. The 8m SOUL looks to be good choice and presents a decent gap from the HL 12m.
Not sure if the 8m SOUL is comparable to a 9m HL in terms in terms of power.
Not yet decided, but thought it was worth asking.
Thanks
