my choice would be the PIV out of the choices and I have owned a PIII as well. The PIV in my opinion is a smaller version of the Puma, which gives you everything you could need, storage, good ride in rough water, decent speed, ect.. Now the only thing you give up is the speed, my PIII would haul. Mine is currently for sale just b/c I want to upgrade to a Puma with a 250 pro Xs
