Your gut told you to go with INT with the live action view you had. You saw everything you needed to see, you were positioned where you needed to be, and you made the call. If you didn't have (much) protesting or complaining, I'd say you made the right call.
I'm my own worst enemy in situations like yours. I'll replay a scenario over and over in my head, wondering if I made the right call. But I've come to realize that my memory of a certain play isn't as good as the live action. If it helps, based on your description, I would've call INT as well.
