Great fins. Feel like my AM2’s

By: on 7 July 2018
I lost one of my AM2 tech flex side fins so I thought I’d give these a go. The flex is very even with a bit more rebound than I felt in my tech flex. I’m running them as a quad and find they have heaps of drive and release well off the top. Finish isn’t as good as the hand foiled fins from Captain Fin or some of the local shapers but I don’t think you can get a better fin for the money. I like them so much I bought a second set in FCS.
