1) They make locking tuners for a reason. Locking nuts are another solution to the same problem. 2) I've never (yet) had a string break at the nut 3) always have a spare when playing live (fool! :D) 4) resetting the fine tuners was the first thing I figured out. Didn't even have to be told.
This guy just sounds frustrated.
I have to say that I bitch, whine, and moan the whole time I am setting up, or restringing a Floyd, but once you get it there, that's it. It's done. It lasts as long as your strings do.
...so ever since then, I always hang on to the buckle.
