Review: Fcs M-7 not as cheap as you think - Wow! I was so stoked upon receiving the fins. It came in the original FCS fin boxing and was well packaged. I thought that the fin was going to be very flexible, but it feels nice and stiff to me. This will be a nice additon to my 7'6 Merrick flyer. For $36 buck, you can't go wrong. I feel very happy that I am purchasing from a USA small business. Very happy with purchase!
Review: kinda stiff but solid - little stiff for me but thats just an ordering error. overall good price and quality
