I'm sorry nobody replied to you back in September Discinfool.
The rule around here on bag tags is that "When you play, all club members on your card have their tags on the line." That's at any round, whether it's a tournament, league or casual round. In October, every year, we do a mandatory 'all-in' tag shuffle at our Club Championships tournament - more like what you were saying above about everyone putting their tag in the pool and they are redistributed at the end of the round. It's a two day event: On Saturday everyone plays for their current years tags. On Sunday, everyone plays for their new year's tags.
I can't make it today, but I hope you find a taker!
