I am selling a 2024 4.1 ENSIS Top Spin wing. This single boom wing is an absolute game changer - amazing handling, direct control, powerful and built tough.Top Spin wings have fast-tracked my learning of different gybes and tacks - having a boom opens up so many possibilities. As an added bonus, you can pack the Top Spin wing up with the boom on, or you can take off the boom for a very compact pack-up (quick and easy).
