To answer your question, you can PD the whole thing, and then WS/GS on any of those days - it's as if they were off days or X days for a RSV pilot. I've never tried it, but I would guess that the PD works like an APD (which I have dropped like this) in that you can only PD one day of the rotation and the whole thing will drop, subject to coverage. It's not as big of a deal with the PD though, because you can pick back up on a PD day.
**I'm 99% sure this is all right, but I have been wrong more times than not. If you really want to be sure you can call 1-800-USA-ALPA and they will be able to tell you in a heartbeat. Put your dues $ to work! 
LL,
You are correct. The only drop days that you can not pick up on are the actual days that the APD (and APD only) touches, not all the days of the pairing.
