hello just got a killer deal on a 15' tri-hull w/a 75hp merc,i would like to learn how to wakeboard,i have experience waterskiing,i know that tri-hulls arent the most desirable for this but im not looking to enter in the x-games,just skip across the water,and occasionally pull the kids in the tube,will those 3 post setups work ok for that or do i need a tower....
