Lee,
I have done a fair amount of experimentation and research on frozen pizza dough and have some thoughts on the subject in your case, but before offering them up can you tell us how long you want to freeze the dough balls before using?
If you do some searching on the forum, you will find many examples of instances where the members have made and frozen dough balls. I think you will find that dough balls have been frozen at just about every stage, including right after making, after refrigerating, or even after a room temperature fermentation. Often the decision to freeze the dough is made on the spur of the moment, typically because something comes up that prevents using the dough balls at that time. When I intentionally make frozen dough, I use many of the techniques used by commercial dough ball producers who supply frozen dough balls to pizzerias, and I make and freeze the dough balls as quickly as possible. I think I am the only member who does that, so you may want to also consider what other members have done on this score, especially since some of them have reported getting good results using methods different than mine.
As background reading on what freezing dough balls is all about, both in a commercial environment and in a home environment, you might want to take a look at Reply 272 at

http://www.pizzamaking.com/forum/index.php/topic,9121.msg83041.html#msg83041, I discussed the results of a conversation I had about frozen dough balls with an employee of Lamonica's, a well-known U.S. supplier of frozen dough balls to pizza operators (including the food courts of Costco, a major membership wholesale chain). In your case, what might dictate the direction to go will be the duration of the freezing of the dough balls you make. There may also be some trade-offs because of the ingredients you want to use, especially the 00 flour.
