Throwing Things

We all know about Killer Croc and "Almost Got 'Im". Here's how he did it:

The AV of the attack equals the thrower's Dexterity. The EV of the attack equals the thrower's Strength.

What's the difference, given a Character with unchanging Dex and Str, between throwing a bean bag and throwing a rock? (It was a BIG rock!)

The Body of the thrown object is the maximum amount of damaging RAPs that can be done to the target. It's a little like Knockback, only the obstacle comes to the opponent.
