18/3 not having the ability to alter the surface between doubles and singles has always confused me. The rule states once competition begins, the ball's surface cannot be altered. If you can't alter between doubles and singles, then you should not be able to alter the ball's surface between team and doubles and singles. I have always considered doubles and singles two separate events, yet USBC is now saying it is one event.
What happens if I bowl doubles one weekend as a sub, then decide to bowl team and singles later? Isn't this allowed? If so, this would classify both events as "separate" events.
I realize I am splitting hairs here, but this part doesn't make sense to me.
I am not a pro-bowler, but I do play one on BallReviews.com
