There must be a lot of ice dancers who love to compete, but don't have a partner other than their coach, so they have trouble going to normal club and regional competitions. So they compete ProAm.
But like the mentioned skater, if they want to coach, they can't coach ice dance, which for many is their strongest skill.
So they have trouble finding students, or charging competitive rates. Imagine the coach bio: "I've tested and competed USFSA Gold and ISU International level Ice Dance - but I can't teach you that. I can teach you the first few levels of LTS." Not the most effective ad!
There could be a competitive outlet for such skaters, dancing with their coaches, that helps rather than hurts their ability to make a living, or the ability of students to take ice dance lessons from them.
Maybe some of those skaters should suggest to the ISI that it could profitably provide such an outlet, if the USFSA won't...
Of course, I could be missing something important again.
