I'd opt for a fleet-style racing series rather than a match race. To me, that would be more representative of what most "average" racers are familiar with. Would give the spectators more to watch, as well.
Although Fleet racing is what most of us know, actually in keel boats as well, I for one would like to see match racing in development class boats like the AC. The reason for my desire is that the handling characteristics that match racing seems to stress (at least in the keel boats) would be great to see developed in multihulls. The jockeying for the start, the need for fast and effective tacking... Of course, to make that happen you need to keep the boats fairly close. In addition to the design elements, it would stress different things for the racers that multis don't usually stress.
