I have never had a problem with ordering sails thru the dealer. EP will not quote direct since each dealer decides his own fate with the margins...
There is a small and growing fleet of I-20's up here in Seattle, although no YC will allow us to race with them (Corinthian Yacht Club) of Seattle refuses to let us in, we as a fleet are racing with the local Hobie fleet and are starting some local races as well...
So far there has been no need/desire to change sails....like most of you, I to am interested in the Formula concept...
Get those Inters up here on a road trip and sail in Seattle for a few days...
