Well JBS, this is just a parent weighing in. Daughter competed L6 last fall. 1st thing we noticed was "wow--the judging is tougher." Yup made L5 look like a walk in the park. I would say the toughest event for all the girls was bars with beam in 2nd place.
Here's my parent impressions---take them for what they're worth.
Vault--if it scored in the low 9s as a L5, it'll be in the high 8s as a L6. Piking, arching, bent arms are hammered by the judges. Stronger, higher and farther seemed to make the most sense to me.
Bars--This seems to be the time to show a non stop bar routine. Do casting drills until the girls want to kill you. They lose quite a bit on poor casting and underswings that don't stay in the hollow position. Also tight legs with toe point and no bent arms. I think the best word for the high bar was attack. Go after those elements. Saw alot of girls just run out of steam or be relieved they had gotten through the low bar section and would just flop around the high bar.
Beam--Yeah--you can hold your breath during an enitre beam routine as a parent! Don't let them lose focus after the BWO!!! I saw alot of girls stick the BWO and then fall on the full turn. Also that jump sequence is rather tricky getting the proper form on the tuck jump.
Floor--Most mistakes I saw were on the front tuck and not hitting the required extension in the leaps. The music didn't do anything for me either.
This is what our girls uptrained on during the L6 year---giants(no grips
til competition season was over), BHS on beam and then BWO-BHS, cartwheel on beam to back tuck into the pit, yurchenko timers(we don't do a formal L7 team) and layouts progressing to 1/2s on floor.
Overall, my daughter scored higher as a L6 than a L5. May have just been getting a year of competition experience. Most of them ended up loving the bar routine once they got past the feeling they would never get a good clear hip and they wouldn't die doing a flyaway.
