Review from Simon Winkley:I like the feel and the shape of the fins and the weight and cost saving compared to G10 is significant. The fact that they are all hand made in the UK by a dedicated windsurfer and skilled engineer is a real plus. I will be using Fang freeride fins for the CarveIQ 114 as well as 3SW freestyle wave and Shark II thrusters for the Kode Wave 103 and 86. Also the K4 Harness Mount will be out there grabbing personal and client images.
