I only know 1 girl who went back to AM because she could not cut it in the real world competitions. She was told she would HAVE to fix her foot technique and learn cuban motion first. She pushed and pushed, was told she wasn't ready to compete yet, finally her instructor took her. She came in dead last at 2 or 3 comps. She was always 1st place at AM comps. She didn't want to fix her (lack of) technique and went back to the AM world.
