I personally hate the sizers sent (especially by GK)... they send NYLON sizers when they know that the team is getting MYSTIQUE leotards - the fit is totally different... plus, over time, the nylon ones get stretched out more.
The sizers HC got this year from AF are much better (it looked like they were mystique, and they DID look tiny - like the actual team leotards).
I agree with passing down the leotards and selling the too smalls... and all chipping in to get the biggest new ones (with the costs defrayed by the selling of the tiny ones).
