The problem with Polar is the flux of the union situation. It all depends who you listen to when making a decision. The previous post on this thread is obviously an Atlas crewmember take and is in no way certain. If you talk to a Polaroid, his take will be just the oppsoite and also is in no way certain. Then there is DHL and no one really know where that is going.
As for the sheer enjoyment, there is nothing batter than slinging big iron around the world. So however you roll the dice, I hope is comes up sevens for you.
