I've been watchin' these boards for a while now and have learned quite a bit. I'm 198 lbs., and surf primarily Trestles, SC. I ride a 6'2" spitfire and a 6' 4" hellfire. Originallly, I tried a 6' 0 SF, but it didn't quite have enough foam for me. I love the SF and the HF in the sizes I have now. Typically, I ride the SF in the Rusty quad, which is fast, loose, with drive. I ride the HF in the SA3 when it gets head high+. I must say, I got caught off guard one day recently and showed up with my SF on a 6-10 face day and it went great. The SF can handle some size. I like the overlap between the two boards. My SF is in RF, HF is in FST. I'm taking both to the Mentawais in a couple weeks, so I'll let ou know how they go there.
