All of you guys can go back and forth screaming "IT DOESN'T MATTER YOU BLITHERING FOOL WE HAVE, LIKE, A VIDEO AND EVERYTHING!" and "WHAT KIND OF MORON ARE YOU, PHYSICS SAYS IT DOES MATTER!" but all I know is that 99% of bowlers bowl on THS.  I also know that THS can make different bowling balls react similarly, or at least close enough that you don't have any inherent disadvantage with either one.  So I honestly fail to see how something that may make two or even three boards of reaction difference, or a foot more of length, has any massive impact.  I'm a god-awful bowler, and even I can change my ball roll enough to move more than that on the approach.

Even if seegeemaddah, THSmaddahmore.  I know, you'll say "Well what about sport conditions you dope?" to which I'd reply, "If you're good enough to be competitive on sport, you should be able to change your release to give you that extra length or whatever.  And even if you can't change it to get the same effect as a different layout, the lane conditions will probably change within 4/5 frames anyways.  Pros can go quite a few games during qualifying using the same ball.  They switch to balls with different layouts on Sundays because those 4 frames DO matter.  But, I remind you, there is only Jeff and a few others on here who don't post, that ever have to worry about that.  The rest of us bowling our wall leagues and occasional tourneys shouldn't be splitting hairs about this, because we'll probably throw enough errant shots that the potential advantage becomes almost useless or our friend the THS will cover up our silly mistakes."

Fire away.  I probably can't answer any rebuttals, since it's kind of obvious I don't really use any inherent logic to make my statements.
