As the gym owner for one of the teams in question...Crimson Heat. I have to voice a clear position on this. First and foremost, there is no right or wrong leg for stunting. There are no policies or regulations which define or specify a standard for stunting on a particular leg. It is accurate that there is a "common" way but common or typical does not mean better.
For years, my program stunted on the opposite leg and was very successful in this industry. Teaching skills like tick-tocks has been a little easier because our kids have balanced for years on the "other" leg and the reality is in college, students may have to fly on either leg especially in pyramids. I have commented on this issue on a similar thread before. Why continue to criticize or critique a team for doing something different especially if it is working for them. It does not make the coach old school or incompetent and it does not in any way make the team or their skills less competitive.
Just let the kids cheer, have fun and do their thing...
I have used Crimson Heat as an example on this subject in a few other threads. I have nothing but the utmost respect for your program, and always look forward to seeing you guys around at competitions! I've been a fan ever since your Sr 3 team wiped the floor with mine at Return to Atlantis about 6 years ago lol. You were not a team I had in mind when starting this thread, but I'm glad you responded. In a world where tick tocks are becoming the norm in all levels, there is definitely an advantage to having a flyer that can pull body positions on both sides. I dont believe, however, that I have seen any college teams who fly on predominantly the left leg in quite some time. Most of the gyms who I know of who once flew on the left are now doing exactly what you've done with 5Alarm and switched to the right. They looked great this year! :)
To me, as a coach, I want my kids to "cheer, have fun, do their thing," but I also want to make sure that I am putting them in a position to succeed in the present and in the future. When they graduate and want to cheer in college, if I haven't given them enough tumbling or prepared them to stunt the "common" way, or taught them the best technique in doing things, then I'll feel so guilty. All the time, I'm seeing kids graduate who I think I could have done better with, and it just makes me feel bad:(
I think the leg issue to me is more an issue that is similar to pleated skirts or keds or teams with neon colors. A team could wear them and still be just as competive, throwing the same skills, etc, but it's more about the aesthetic. (Though, Bangkok with their little pleated skirts are still the DEAL lol) :)
