YS question:

If someone is FULL but still wants to fly on their FULL RES days would a "First for Flying On On-Call Days," YS would be appropriate? Since I no longer appear on the Reserve Availability List (because I'm FULL) I'm not sure this will work.

Where does a "High Yellow" fit in the coverage ladder? I don't see it -- only a YS for flying on/interrupting X-days.

Or is the only option a GS?
