MacKite Boarding has done some great reviews on V2 SlingWing.
I am going to get a 5.4 when available in AUS.
I have used a 5m F1 SWing and a 5m Wasp and the V2 SlingWing looks to have the best features of both.
Hopefully you get a little more low end grunt and more stability when free foiling, the 5m Wasp does swing around a bit when free foiling in over 25 knot conditions.
I ride in conditions that can vary from 15 to 20 plus knots during a session and I opt for a bigger wing to get me through the Lulls
The squared of wing tips looks like a great feature
Will update with user review when I get my hands on one ( back to back with a 5m WaspV1)
