I never had a standup before but have been riding jet skis for years. I am bored of not being able to jump and do some stupid stuff. I have jet skis to ride around in so I'm looking for something more for freestyle use. I weigh 250 lbs and that is what I am trying to overcome. I know that everyone has their opinion but what would be best for me, 750, 650, 550, 550 with a 650 conversion.... I have great balance and I'm not worried about top end speed,just enough torque or hull shot to have fun if I'm thinking correctly. I am very mechanically able to do a conversion so I'm not afraid of doing that if that is what is best. I just don't know what hull is best for fun.
