Future Fins Lost Slingshot Quad Surfboard Fin set

I surf in Huntington Beach CA and ride primarily a lost 5'6" Bean Bag... I have been using Seaworthy fins until now... The Slingshot fins rip they add an extra dimention when it comes to huge cutbacks! I think the speed and drive are similar to the Seaworthy fins. Using Seaworthy fins you just can't lay into a cut back at high speed like you can with the Slingshot fins. I have had 4 sessions with these plugged in, in about 3 - 5 foot surf and I will not be taking them out... I stil think that the the Seaworthy fins are a great option but I recommend getting yourself a set of Slingshots you can't go wrong!
