I am assuming you are talking about coastal fishing, as that is the only place I have ever seen them used. Were it me, I wouldn't get one. What they gain in shallow draft, they more than lose elsewhere. Overall speed is significantly lower, maneuverability is lessened, they don't back up worth diddley. Now, on fiberglass vee shaped flats boats with tunnel hulls, there isn't much of a difference as far as how they ride in rough water. However, and this next statement is just my own hypothesis, I think a standard aluminum mod vee tunnel won't like rough water. Were it me, I would likely go for a standard mod vee with a jack plate that has a significant setback (the more setback you have, the higher the motor can go). I would have the hull fitted with some sort of trim tabs, or those boxes that some of the aluminum flats boats (not a brand that I hear to much about - but I saw at the boat show - can't remember it for the life of me) that act as both trim tabs, as well as step.
