No I do not brief F-Hot. I buy my fins from F-Hot. Because I am a normal guy, I can only test against my old fins (Select and Tectonics).
F-hot supply the fins with any rake you want as different sailors like different styles. If sailors do not ask for a particular rake, f-hot set it at 3 degrees as an all-rounder.
I tried both 3 and 5 degrees, for me personally I like 5 degrees, so I change all mine to 5 degrees
Steve Cook from F-Hot developed the fin, check F-hot out, they have many years experience in carbon composites.
Just to be clear, F-Hot do not sponsor me, I am a normal guy who like to have good kit and sail as fast as I can, but I can not afford fins like IJU or CA etc which is why I love great value fins like F-Hot. I took a chance on F-Hot and they are working great. If I had not got F-hot, I probably would have got the new Drake DW or Select V-max. Some times we just have to take a gamble on a brand. I am much lower standard than the PWA guys
