One of the best selling MC boats is the X-2. With the wakeplate properly adjusted, it can pull a slalom skier through the course. It is not great, but it does work. It is MCs best selling hull. It is really hard making a no-compromise boat for a narrow audience that will pay off. Most buyers have a family and several conflicting interests and uses. Also, most boats don't wear out. You can keep them going for decades. If you like your tow boat, keep up basic maintenance, and replace the soft surfaces every 5-10 years, you essentially have a "new" boat for a long time.
It is really tough to be a boat manufacturer. You are essentially following or creating fads of what the boat buying public wants. Wakeboarding was really popular while it was new and tricks were new. Anyone could get "good" because the top end was undefined. Any competitive sport or activity shares this characteristic. Then, the beginners start of fade off because the top end is so far away. It is frustrating because people want to be competent and good.
The upper end of waterskiing is so far away that people want to "throw in the towel" because you simply have no hope of getting there. So, why spend over $50k for an activity or sport where you cannot compete. There has to be another reason. For me it is the lifestyle and the simple enjoyment of my family. So, for now I have an X-2, slalom behind it, and slalom behind friend's boats. When the kids are out of the house, I may get the next version of the 197 and slalom exclusively.
Right now, I am thankful that MC, CC, and Bu make slalom tugs. Hopefully I can get one in a few years.
