Berny,
very interesting to hear that you felt handicapped upwind with the spi gear. Have you done any testing to see wether it was the spi pole, the snuffer or the complete package that made the difference? If it was the snuffer, perhaps a "snail" system like what Marstrøm use on the M20 might be better?
I dont like sailing triangle courses with the spi..
Bad luck comes in heaps, and you was hit badly this time. I bet Mr. Murphy is having a very good time with you and the participants at the F-18 worlds.
I can only second what John said, hope to hear more about your 430 soon.
