If your touch on these very short very soft shots is good, and if the balls were really positioned exactly as diagrammed, the safety is pretty much unmissable. As an added benefit, if you play it right, the 8 remains parked right over the hole where even if he hooks you back you should be a favorite to kick it in. And it's not likely at all that he hooks you back.
The bank is not a very tough one, but is definitely missable. And if you miss it against a good player, it's a definite sellout unless you get very lucky.
The safety is very clearly the percentage play here, to my eyes. But if you change the positions of the balls even subtly, the safety could get a lot more missable, and that absolutely changes the equation. So if it's possible that you're mis-remembering the layout at all, that could easily explain your captain's (and opponent's) opinions.
