Recommended ice scoop size

I see quite a few sizes of ice scoops measured in ounces. I've used some that are way too big and others too small. Basically looking for the right size to fill two pint glasses with ice in one scoop. A small thing that becomes very important.

The scoops are usually measured by ounces but I'm guessing that the measured size is liquid ounces filled to the top of the scoop, not the amount of ice.

I'm guessing a heaping scoop of ice in a 16 oz scoop would fill 2 16 oz pint glasses? Or should I be looking at a 32 oz which seems like it might be too big?

What is your recommended size scoop?
