This is covered in the documentation page on Families. But, if you are like me and tend to glance over some blocks of text in the middle of lots of blocks of text, you may miss this simple fact.

Extremely Powerful Tip:
Create a BaseSprite family that the majority of your game Sprites belong to. This will allow you to work with the basic sprite properties very easily and efficiently. You can then further organize into more specific families as needed.
