dude? really, trimming the wings?
I mean, alright. Some people don't empathize with bugs, so w/e. I try to.

But from a practical point of view, damaging your crickets (no matter how insignificant seeming) is a great way to spread disease into your colony. They might also be less effective at breeding, since those sounds are meant to facilitate breeding.
It's possible your experience has been different though
