I owned an X9 as our first MasterCraft. It was a great family all around boat. We did every watersport behind that boat when we started out with the kids. Tons of room and the quality was amazing. When we bought a place on a lake with buoy chasers and I joined up we switched to a ProStar for the course. The slalom wake and driving the X9 in the course will not be as good as a 197.
Is the Outback a V drive? If that was the case I would for sure pic the X9
Overall my recommendation would be to pick a X7/197, Bu lXi, or SN 206.
