I only spoke to Matt briefly. The weight is at or near minimum, the rocker is farther forward than the Blade. The obvious visual difference is hull volume. The Falcon seems to have more volume than either the Viper or the Blade. There is a "hump" (saddle?) that the rear cross bar sits in.

I could not tell any difference in performance. M&G rock regardless of the boat they are sailing!

I couldn't tell any difference in the sails, Glasers, but wasn't really looking.

The Falcon uses a high aspect board.
