I was speaking with a bowler in a Ladder Match and mentioned about having been victim too many times by 300 shooters. I've been thinking, since the top 10 are so good, why shouldn't they have to bowl with a different type ball each Strike shot ? Most can use any ball basically anyway, so why not, for those of that don't ring up 12 in a row the majority of the time.
That's my suggestion, for tourney's or ladder matches.
What do you think ?
