I worry about spinners. I think the more intricate and cool your design is the more likely it is to get damaged by a spinner. For instance if you made a really cool pair of jaws, they'd get ripped straight off at the first spinner that clipped them lol. I've been thinking about spinners and what it would take to not only survive, but also fight back. I think the basic gist is to have something angled you can stuff in the blade that will stop the blade, but also deflect a lot of the energy. I think I have a good idea for this, and also for drums since most drums spin upwards. I'll sketch what I mean later and stick it up here lol.
