I've suggested, several times, to Nico to provide ball credit/voucher instead of the ball they provide. He says, "good idea" but never follows through.
Balls affect the meter speed, the distance, the spin etc... I'm not good enough to bounce beween drastically different balls. I have won dozens of balls that I don't need or want. I would gladly trade a dozen Bridgestones for a sleeve I desire.

MMOC0528: I'm still wondering about the prize balls from Showdowns
In rookie you will win the level 47 TM balls (they don't change), in veteran you will win the level 40 Titleist balls (again, they don't change), and for the Royale Showdowns you will the level 0 Bridgestone balls (again, they don't change).
