hmm, i always pay the most out for the crew and stick with them the whole way through - get packie mcreary from a random event right near franklin's aunt's house, and pick up a driver along the north of the island (can't remember name) - use them, as the driver has good specs and only asks for 5%.
is it the drill method that gets most at the end? i went in the sneaky way, may have to try it another way this time around.
doing the 5 miles through the desert at the moment for the epsilon stuff - headlamp holding movement left and weight on X so he'll run in circles while i browse the internets that'll rack it up.
