Question for the Hive Mind.

We recently tried the Furball multiplayer format for the first time and it was awesome, totally recommended!

But does anyone else who plays have a good way for determining initiative if multiple players have ships of the same pilot skill?

And since it is a "one ship at a time" on the board, would you have initiative staying the same or would you change/reroll when new ships of the same PS arrive on the board?

Thanks for your thoughts
