The loud approach is the more difficult as some of your hacked time is taken up with crowd control. The smart approach lets you steal jewelry uninterrupted making the mission easier to complete.
The more expensive driver will give you directions and select bikes suited to the course. But the cheaper driver does his job. Stay behind the other crew to let you know where you are going and the road bikes don’t handle too bad in the mud.
If you choose the cheap gunman he will crash his bike and you will loose a substantial part of the money.
Depending on which hacker you choose you will have different amounts of time. I found that Christian Felts gave me just enough time to take all the jewelry.

Protip: If you choose the cheap gunman he will crash but you can bike over where he crashes and pick up the dropped loot.
the best set up is Eddie ,Norm ,Rickie (pick gunman loot)
Craw Cut Eddie,Rickie get (3xx,xxx)
Money Loot (any loot money go to playable char Craw get nothing )
Michael get 45.5% (he should get (9xx,xxx) + half of the loot from Norm)
Frankin get 12% (2xx,xxx) + half of the loot from Norm)
Lester get his 14%
with the best in the team you would have to pay the craw 1,051,847 mil
and pay 2.5 mil for the house with a take of 4,946,153 giving you 1,394,306
im sure u can work out the rest (m 45.5%, F 12%, L 14%
i found a even better set up
Eddie,Gustavo and ricky
take 4.9mil
when i went on the roof and it said throw the smoke bombs i checked in my inventory and i dont have any just a grenade where do i get the smoke bombs from ?
“If you choose the cheap gunman he will crash his bike and you will loose a substantial part of the money.”
I did this, but you can actually drive over the guy to pick up the money, so then you don’t lose anything and it is payed out to less people.
Good point.
HOWEVER you still loose money for casuality cost around 300k, so with the better gunman youll make over a mil
