See, the problem with all of these options is that they require Luffy to think about them. Luffy doesn't think. At most he incorporates the ideas of others if it matches his mood and general agenda.
It's fine, what is good with that it's that Luffy can count on his mates to do things like this, most of the time he doesn't listen and end up doing it his own way though.(water seven when he was supposed to sneak in and got stuck between buildings cause he jumped, enies lobby when he just went ahead and start beating up the marines)
Now it's a delicate situation so he must think a tiny bit or listen to what the others has to say and stick to it.
