I don't know for how many years I have had these flexible plastic clamps on my rims, used by how many sound engineers, but it's amazing how easy these click on your drums, and how hard it is to hit them from their spot.
Almost not possible, or you have to deliberately aim at them. I have never hit one off, not even on first time drum kits placed permanently in certain venues.
You'll more likely break the mic. attached, but the clamp itself will remain on exact the same spot.
Which you wouldn't think by looking at it, but as I said: Sennheiser have had this for many many years.
These are meant for toms en everything else with similar rims, you can even put these on almost any snare and not be worried about striking them off.
It's that flexible material of these things that does miracles.
It absorbs your miss-hits.
A must for any drummer who mikes his/her set.
