If I review S/A`s 3 junior season, I would say that Kustarova did a good job improving them from season to season. When they first came to the scene, they were already good, they managed to qualify right away for the JGPF, but they were very messy and uncontrolled with flying arms and legs all over the place. Starting with their last year`s blues, there was a real change in their overall skating, much more in control with great lines and better unison. As it was stated in here, the move up to seniors is unbelievable hard, teams like Parsons or L/D who were both crushing their competition in their last junior season really struggled this season. Although, a part of it were the program choices the coaches made for them.
I`m not so worried about the Short Dance, since I expect the tango being a good fit for S/A, my fear is that Kustarova is going to stuck them with a weird music choice for the FD just for the sake of standing out.
