I did think there were some good post-Byrne stories.
I also liked:
The two Alpha Flight Annuals of the Volume 1 run
The Alpha Flight Special with "First Flight"
The second AF/X-Men two-issue mini-series, (although the first one, "The Gift" still rules!)
Rom #56 - 58, (and why wasn't Mantlo this good in the regular AF book?)
Wolverine #143 (with the return of Snowbird -- I was glad to see her back, in spite of the fact that it didn't make sense)
Wolverine #172 and 179
Black Panther #43 (with brief but good AF appearance)
and X-Men Unlimited #45, (with the birth of the Hudson baby -- and will someone PLEASE give her a name?).
Hopefully, someday, we'll get a Volume 4 that will be as good as these issues. Or even better!
