Reaching starts don't work well with lots of boats.. We tried it during the America's Cup World Series, kind of by accident. All the boats got to the windward mark at the same time and the leeward mark for that matter. Scary
Scary yes... but also awesome. Those races were also about ten minutes long, so not much time to separate.
Personally, I would rather a standard start, but having a trapezoid or something with a reach would be fun.
This will be my first F16 regatta...
