my suggestion to you bro, since you're doing this for business...i have a friend who also runs a band rehearsal studio. what he did was he used a sabian b8 ride cymbal as a crash. before, he needs to replace his crash cymbal every three months. now, his problem is solved.
just install a regular crash if you know the drummer of the band or if you know that the drummer is not an amateur.
my 2 cents for you.
