This maybe should be in the board review section. I have just returned from a surf trip in Indo. I took my brand new JL 9'1 Kwad. On the first day surfing a soft small beachie I somehow lost one of my rear fins. The next day I customized a FCS fin to fit into the Futures fin box (NB. rear Futures fins from quad setup have a slightly different setup to the regular Futures setup and therefore regular Futures will not fit). My first surf after repair job the board flipped during a wipeout and I landed on all 4 fins slashing my elbow and knocking out repaired fin. For the rest of the trip I surfed with only 3 fins. The set up was suited to my forehand and my backhand was at times a bit spinny but no real dramas just less down the line drive. I had plenty of spare fins just no rear Future quad fins! Hope you enjoy the photos, unfortunately all lefts although had lots of great rights.
