I had one of the newer models that had the diab foam glassed into the floor. I had it out in some moderately rough water. It performed great. The only reason I sold it was because I bought a Dave Clark Estuary and didn't have room to store them both. Otherwise, I'd still have it. That boat flew with a 2 stoke 15 hp, scary fast!
The main issue i remember reading about was the floor flexing quite a bit. Never had that problem with the foam in the floor. If you find one without it, it looks real easy to do yourself.
My main gripe was that the dodger didn't fit nice and snug after it was snapped down.
I hope that helps you out. If you have any other questions, feel free.
