I would think that allot of it too would have to do with the hull design, correct me if I' m wrong. It's my understanding that for example the Donzi Blackhawk is much faster with them than when people switch them to Bravos. One drawback is that with the speed comes some Flightiness. Kind of a trade-off. I would find out what the manufacturer recommends as they know what the hull is best suited for.
