We're now running this list in Nova Scotia:
Starter:
Battlefield
Smashville
Lylat Cruise
Kongo 64
Wuhu Island
Delfino Plaza
Duck Hunt
Counterpick:
Halberd
Omega Gaur Plains*
City & Town
Skyloft
Windy Hill
Wooly World
Castle Siege
If you're not going to run regular FD, then run Omega Gaur Plains as a starter. I don't see why FD shouldn't be in the list of starters, as it's the most basic stage that exist, hasn't changed for the past 2 games in its flat layout, and has been working in the starters list for the past 2 games.
I'd put either Wuhu or Delfino as a counterpick and leave the other one as a starter. One stage that moves around an entire island is enough, both also have some mildly intrusive landing areas.
I think Town and City is fine as a counterpick. Platforms leaving present some minor problems.
I'm not a big fan of Skyloft, some areas are janky. Wooly World and Windy Hill seem to big, in my opinon, but it might be worth testing them.
It's a good stage list though, and that FD link you provided is pretty good to give us an idea of how Omega stages can be classified. Thanks!
