Not to be too pedantic, but it was 3 of the 7 in classics (Vancouver Flip-Out Tournaments).
My point is that, in my opinion, classics should play like classics - no fancy lightweight balls, no super-bands or synthetic rubber, LEDs are questionable but tolerated.
As a data-point, I searched for “Glo Ball” on these forums and this and last year’s Vancouver FlipOut threads were the only 2 matches. I don’t see them as being equal to the other examples as tools in your tool chest.
However, I get that you can only do what you can do given the circumstances, and wish you nothing but the best with the tournament. I’m sure I’ll play the glo-balled games if necessary, but that doesn’t mean that I’ll like it.
