As much as I like the AOA folks for volleyball (which is their specialty), I've never been satisfied with their sixman football group since the time we had our first junior high playoffs several years ago when they bailed two days before and we ended up having no officials to call five or six games that day.
I didn't think they had many officials in their football group.
Brother Robert the first, I'd start using TASO San Antonio for your games. If they're half as good as the guys we get from TASO Austin, you'll have no problems.
