So, if I had to put together a team to do a heist made up of SHL users I feel like the team would go as follows:
The Brain - would have to be me, not because I value myself as a criminal mastermind or anything, but it would be weird to be planning a heist and assembling the team without being the one had the plan and leadership role.
The Brawn - Would be Justin Keahi. I am positive that he could fight a wall and win so I have no issues using him if we need some enforcement. 
The Wildcard - Would be Adam Friedland. Anyone who has interacted with him would get what I mean.
