Excellent article. My experiences are similar. I didn't have the full blown race kit but it's still fun and it pushes your skills up a healthy notch. Well written and worth it to get the word out especially for those banging on "it costs 10k to race". The Starboard Race Alu is another option plus there are others with wings from 800-1000.
I should add that most race organizers are very sensitive to the cost aspect and are quite willing to have a "freeride" class if they can get enough participants. Obviously, as something like the Nat Championships it may not happen but certainly at regional events they want to include as many people as possible. If they can get 3-5 people on the line with freeride foils and everybody is willing, you'll have a race. Just don't be shocked when the dedicated race gear laps you...

Last thing for us older buzzards - even if the chances of you getting a trophy are nil, remember that your signing up enables someone younger to have the opportunity to race and grow the sport. This is your chance to pay it forward.
