Fox 40 Whistles with rubber mouth grip

[jTheUmp]

I use the CMG whistles... I go through about 2 a season... about 50 games apiece, give or take.

I don't rotate them, I use one until the grip wears out, then I replace it with a new one.

At $6/whistle, that means the whistle costs me about $0.12/game.... hardly worth worrying about.

Do you bite the whistle, or do you hold it with your lips? Methinks that holding it with the lips would make the cushion last longer.... I'm a biter though.
