Your numbers are a little off re: wide-body %
A May 2005 hire would be 100% on the Bus -- probably 5 guys from the bottom of the entire F/O list. A little better on the -11, still @ 100%, but about 60 guys from the bottom of the list.
ANC would be a little better, not sure if you want the commute for 80% (or so) Seniority with diminishing lines.
If the excess rumors are true, then your seniority would not let you hold the Bus.
