My stigma for Cayo

I’ve built this heist up so much in my own head that I’m scared to even consider attempting it. I’ve done it once, with 3 other randoms, I mainly stayed back, got a bag full of coke and deservedly ended up with the bronze award for it.

Mainly a solo player so don’t want to drop into random lobbies and risk ruining anyone else’s attempt at it.

I think I know the answer but am I over thinking it?

I know it’s possible but how is it to run solo?
