I am sure this has been asked before, but I am trying to get clarification for a player.
It says on page 8 of the rulebook a player may measure to see if his ship can preform a barrel roll before committing to this action.
My question is if a player wants to preform a barrel roll to the left and places the template down on the table and nothing would obstructe the barrel roll can he still decide to pick the template up and do a barrel roll to the right?
