Having had my first taste of the format this weekend, I have to say I really liked it a lot.
For those who aren't familiar, the Hangar Bay format has you build two unique lists. You cannot duplicate any pilots, ship models, or upgrades between the two lists, so using VI in one list will lock you out of it in a second. You reveal both lists to your opponent at the start of setup, designate them as either #1 or #2, and decide which one to play by setting a maneuver dial.
My favorite part of the format is how it helps mitigate some of the Rock-Paper-Scissors issues that comes up during list building. If your opponent brings a list that you would be weak against, you have a backup list that you can turn to instead.
As an example, I ran a Heragator/Ahsoka list alongside a Kylo Oicunn/Quickdraw list. I had planned to use the Hera list as my primary, and was able to do so in my first match. However, my next two opponents had PS9+ in both of their lists, making Ahsoka vulnerable. So instead, I ran my Oicunn list.
I'm thinking that making this a default format might also help alleviate some of the issues involved in a specific list becoming THE LIST. You can have your list that you think will do well against Parattani, and still have a list capable of fighting all the things that are problematic for your first list.
The obvious downside is that it will double the price of list-building for new players entering their first tourney.
Thoughts?
