This is an idea I feel the USBC should look into and passing a rule for every sanctioned league out there. It's really a page out of the PBA's rules. I really feel it is possible and would be a good thing. This would be a USBC rule, not a league rule because I would be willing to bet on most diverse handicap leagues people would not go for it.

First thing is regarding warm up time. Brunswick seems to have a rule about the amount of practice time. For whatever reason, the only time your aloud to get 15 minutes of practice is you have to have a 5 man team league. If you have a 4 man league team then you only get 10. If you have a 2 man team you get 10. Makes 0 sense to me. I say USBC has it across the board and make it 15 minutes for any sanctioned league.
The second part of this rule is the amount of balls you are aloud to throw when you are warming up. Every league I have been on, if you get a strike you go to the back of the line or to the other lane. If you get less then a strike you get to go again. Big time delays. From now on, USBC should have a ruling just like the PBA and you get to throw one ball no matter what you leave. The next person is not aloud to recycle. Whatever is up there, you shoot at. What is the point of this? To speed things up. I would like to throw more then 3-4 balls in practice if I'm lucky. With this system, I should be able to throw twice that.
