b) locking down your recursive servers to networks you control

Sure.  But OpenDNS, Google, and the other providers of recursive servers
for edge cases can't do that anymore?

I wish people would stop bring that up.

I guarantee I see at least as many reflection attack as anyone out there. I have not _once_ called/emailed Open, 
Google, Dyn, Ultra, or any other professional DNS provider asking them to stop amplifying attacks to us.

If you can run a server as competently as they can, then no one will complain.

For the other 99.99999999% of you, LOCK THAT SHIT DOWN.
