We've had better luck with a 2003 Malibu Response Lxi than the Sunsetter Lxi. Granted, the Sunsetter has more room, but the response has a better slalom wake. It also has a better surf wake (groan) because you can attach a wedge further to the back of the Response. The Sunsetter has a cutout at the back so the wedge didn't work as well. Also, the Response turns a nice tight turn and is easier to maneuver and can do bat turns. The tower on my Response only weights 40 lbs. Advantages of direct drive, is better speed control, better visibility for wakeboarding since the front stays down, and easier to get into after skiing because the ski platform goes all the way across and is at water level. Plus no prop to worry about when swimming back there. The advantage of stern drive I/O's is it's easier to steer when backing up, and you can raise the prop for shallow water or when pulling up to put it on the shore.
