false double foul question/ and block/charge

[mutantducky]

ehhh....Had this a few days ago. I guess I had a chance to call one and I passed. Doh!
A1 drives the lane, gets fouled by B1 on the arm, and then right after commits a charging.
I called the defensive foul and I heard a fan go "what about the charge" and by golly that fan was right (which they usually are as us refs know)
I had it as a non-shooting foul. But if I had called it, do I just do the double foul motion? and then POI on the endline. The first foul clearly came first but I could have called both.
Another weird play I had was with the offensive player on a drive. The defender is a bit late. So I'm set to call a block. But the offensive play looses his balance a bit, and is forced to slow, and in doing so kind of leans in and makes a move with his shoulder where I could have called an offensive foul. I find those calls a bit tough to call. The offensive player is making an aggressive move. He is trying to draw contact but the defender isn't set. Sometimes they can be clear offensive fouls but this was was really borderline.
After I was thinking that I could have called a blarge (one ref!) but honestly that's what it was. Two basically simultaneous fouls one by the offensive player and one by the defender for not being in LGP. It was really hard to tell what came first, it seemed to be that there was the illegal contact by the defender and then the shoulder came in to clear the defender. It was a no-win situation for sure. But at the same time I did think, why not call it like the first situation. I know it is easier to call a block or a charge but I could have called a double foul.
