I would like to add that unseen and misunderstood double-hits are the bane of my existence. I call these fouls on my teammates anytime it happens, even once on a made 8-ball shot to win their match. I would prefer my teammates have integrity, rather than a good win/loss ratio.
I would also like to point out that, in the rule book downloaded directly from the APA website, poolplayers.com, it specifically mentions that a double-hit is a foul in two places. In my experience, too many people in the APA take word-of-mouth rules as the "The Word" instead of looking at the actual rule book. Please disregard this statement if your local bylaws have an exception to the double-hit rule. Many people try to claim that this rule doesn't apply to SL4s or lower, but this is not the case.
If you need some help educating your fellow players, put this YouTube video on your cellphone and show it to repeat offenders while you are practicing. Compliments of Dr. Dave Billiards: http://www.youtube.com/watch?v=ubbAzu_sCS4&list=PL650CAC26A955DCF8
It shows many different types of double-hits, including those that people believe can be avoided simply by jacking up their cue. This should help you explain the physics behind the offense.
