Daniel:
The DTX will endure ant amount of torture you could inflict on it 
during teaching sessions. As ED pointed out in an earlier response, 
the cymbal wedges are the most fragile, but I can't imagine that 
would not hold up in your application.
I did crack a wedge, but that was in a 'live' situation playing with 
a rock band. Even after the crack appeared, the cymbal continued to 
function normally.
