I don't think anyone is in any big hurry to break the century mark with the 28. Short boats tend to become a bit on the twitchy side at about that speed. As I think about it, my guess is that most guys that want a boat in that size that has great flat-water performance are shopping for Fountains and such.
On the other hand, the Brave is probably the best boat I've ever seen running 70 mph in sloppy water. Running side-by-side with a 35 Fountain on a nasty day, you'd be surprised at how the passengers are getting hammered in the other boat.
