Well I figured before you get to the island, you're going to be on the mainland in some type of civilized atmosphere--So, rent all the stuff for multiple days and take it from there to the island. Spending as much time before you depart for the islandin the shop talking "shop" with the guys. Get on the phone and call them now and develop a relationship with some of the shop clerks who answer the phone there (mainland pro shop). Stroke their egos and maybe they'll remember you as the crazy american who calls all the time. There's gotta be a shop between the airport and the island. Find it and pump them for info and equipment. spread whatever budgeted money around there. I know you're a fisherman. Is there anything better than local (regional) info?
