Tiffani definitely has a lot of charm and charisma on ice. She & her brother never got to the top of podium due to various injuries. I believe she is considered somewhat tall for pairs skating.
She may be taking ballroom dance class to keep up with the 'dance' aspects of ballroom dance.
Don't forget, big sister Stephanie was John Zimmerman's partner before she had a wrist injury. When they split, John partnered with Kyoko.
