I used to carry a mini, but didn't even realize it. Honestly, I didn't pay that much attention; I just bought the Fox 40 and didn't even notice "classic" or "mini."
Then, in my first varsity game, my partner's critique after the game included the fact that he could tell I was using a mini, and it was hard for him to hear me on the court. Had nothing to do with uniformity, however; only the inability of your partner to hear your whistle in a packed gym.
Had him for a partner again in an AAU tourney later that year, and during the first break in action he came up and commented that the new whistle sounded good.
