Yea good luck with the dress code being enforced and the max of 4 or 5 balls.. Just never going to happen.
I am all for dress code, but many bowlers have the thought process of I spend all kinds of money to get there, hotel, entry, food, etc.. Then on top of that your going to tell me what I can and cannot wear. They accept what we have now. Anything more would lose entries and we know USBC doesn't want that.
The ball issue, take as many as you want. Chances are you won't use but 2-3 anyway.
