After much thought, I think I will be purchasing a Spitfire in the next couple of months. Last year I was pretty stoked on the Potatonator, but it seems just a little too flat and boxy and never bought it. Unfortunately, I do ride thigh to shoulder high gutless waves most of the time here in South Carolina. I'm 6'2", 170 and fit, normally ride a 6'4" shortboard, so I'm thinking 6'0" in the Spitfire. I prefer FCS fins, but I really don't know which way to go on construction. I like the option of White Rapidfire, first because it's white. I'm assuming it has the same slightly lower cost as the regular Rapidfire, and it does not need the goretex vent. I have also heard the top deck on Rapidfire's seems even more durable than FST. That being said, if I'm spending this much, upgrading to the FST does not bother me much. Again, I like the white and balsa rails look great in the FST. The lighter blank and vent are slightly concerning, but I've never broken a Poly board before, so it should only be stronger, right? Is there anything else I need to consider? Does one float higher than the other? Is there any notable difference in durability? Thanks for the feedback. One more quick question. I've never ridden a Quad. In 3-4' not completely mushy waves, should I find a Quad faster, quicker in turns than the thruster?
