None of the above mentioned... go LokBox. It will allow you to dial in your boards much better than FCS or Futures. Besides, you can use FCS or Future fins in LokBox if you desire. Do some research, there is more out there than just Oneill and Buildabong, CI and Rusty, Futures and FCS. Everything about LokBox is better, FCS just came out first and has good marketing. they do have several good fins, but the bases are not the quality that LokBox offers, and with FC/Futures, you are limited to the exact fin location that the glasser or fin guy installed. With LokBox you can move the fins up or back, for looser or tighter feel. 90% of my boards are glass on. The ones that aren't I use LokBox. No, I don't work for them. I just know they are good people with a good product.
Not to happy with futures at the moment as I bought a new board last week with their system and already ripped a fin box out. FCS has always seemed pretty durable but i would like to try lokbox.
I've been satisfied with the Futures. The fin boxes have been durable - I certainly have scraped enough reefs over the years. Most of my boards have been Futures so it saves on having so many duplicate fins just for different box types. LokBox design is enticing but there hadn't been much fin selection when I started building up my Futures inventory - also, I don't need to tweak the positioning of my sidebites as much as use different fin templates & sizes.
Did you know that you can use Futures or FCS with LokBox? They have a part that allows you to use any FCS or futures with them. ProBox is a pretty cool set up for me as well, but I'm not sure that I can handle adjusting the placement as well as the degree of angle for the fin. Back and forth, cool... degree of angle... too much for me, lol. LokBox has a stronger base than FCS or Futures. Inmyhumbleopinion.
any fin is good for me i have 4 boards with all different fins Fish: Loxbox High performance shortboard: Futures Small wave board: FCS Funboard: FCS Each works fine with me. To me as long as the fin is good i don't really care where its from or the company logo.
