I would say taking cash is best
LDO. You stand in the middle of the Rio and swap out the cash with people for MB/Stars +5% Then you get full value for the loot and no security risk flying home with it. When you get home, you can pay people by MB/Stars (particularly those that paid you that way).
At that point you can decide to screw your mates and keep the vig, pass on the vig pro rated to backers, depends largely on individual character.
What amazes me in the poker world is how bad people are at this stuff. They can spend hundreds of hours fine-tuning their stats in obscure spots on the turn taht result in 0.002% improvement, but can't spend half an hour preventing Uncle Sam from taking 30% or from Barclays taking 5%
And just in case there's any doubt, when you swap with Barclays, they really do mean 5% of everything.
There is another way, open a USD account in Vegas and pay it in. WIth a little bit of fore-thought, you can work out how to get that back to everyone intact.
