I designed a private lake for wakeboarding. It also houses the jump. It is deeper than the slalom specific lakes with a unique bottom shape to let the boat settle in but punch up the wakes at 75-90 feet.
There is a very different vibe between 3-event and wakeboarding. Even in a 3-event boat set up for tricking, you don't have 8-10 people jamming to the tunes. 3-event boats have minimal personnel. Personally, I have a wakeboard boat with 2,100 ballast and surf more than anything else - because the kids like it so much. I cannot get them, right now, to sit on the dock or shore and watch slalom waiting for their turn. It is not as much fun as in the boat. As Dad, I really like the kids all around laughing, making videos (Vine), and posting photos to Facebook and Instagram of the rider's run - especially if there is a great yard sale.
I like the 2-event format - slalom and wakeboard. Those are the two biggest events, so put them together. I run both, so it works for me. At my age, I don't throw inverts, but I still have fun on the wakeboard. I still prefer slalom. However, I will do whatever I can with my kids around me.
