A couple of things:
-lower your expectations if you don't have that TOW, guys at the top are fast and will only be faster as they also probably are much better t getting the new kit tuned in
-start here, http://www.carbonsugar.com/

-the new generaion of fins require a different style of sailing that probably most sailor won't be able to pick up straightaway hence the rubbish rumors about this fin doesn't work etc...
