the simons are bigger and some of that is tip area rather than a massive base...because of this they work well in wider tails...just like they would of in his early thrusters.!!..they dont do so well in narrow tails with all that tip...for example, the opposite is the am2's which are larger again, but have most of it at the base and less in the tip, they are free and easy in narrow tails, but can lack a bit of drive in the wider tails.....i like tip area in my fins...its where i get my drive...so i use simons in wider tails and jc's in narrower tails..both templates have medium bases and fullish tips...its good to know what works for you...then go bigger or smaller as required....
Thanks for clarifying. I have the Stretch large, set up as a quad on my 604. I am taking her out for her maiden voyage in an hour in some pathetic - but uncharacteristically warm - surf. Cheers.
