I just recieved a whole bunch of fins from F-Hot so I spent the day testing them all. Had some differnt stiffnesses, some different thickness of foils and some different outlines. For general all around usage you cant beat the RWS 3. So good all around and in open water its amazing. I did find another that maybe has better potential purely for some speed runs. Today was not the day to go really fast, but I cant wait to try this fin on the next good day. I think it will fly!
