i can understand the tumbling requirements to now be on a team due to competitiveness. But gosh im so glad a i aged out when i did or i would have never been able to be on a level 5 team.
When i was at the level 5 division the only tumbling required to be/stay on the team was jumps to a standing back tuck. They liked if you had some form of running full but it wasnt a true requirement for the team. I could manage a running full, and the jankiest of punch fronts to a tumbling pass. The biggest factor at least when i was in the coed division was that your biggest strength was to be a flyer, if i can remember correctly, we only had 3 or 4 girls who didnt fly.
