Don't know if it applies..
I rode Sanoman's ROK when he visited a while ago. (pre-freak).
As an sj rider I find it hard to make any kind of judgement when it comes to AM hulls. Not because of the hulls, but because of the extreme power plants that they often contain.
Don's ROK had reasonable x-scream power and I rode it in surf.
It took some getting-used to, but I thought it was great. Could not make it pearl, turned on a dime, lots of room in the tray.
I felt that it would be a great surf boat. I know nothing of flat water.
