It would be interesting to know why 8 ball was selected as the game for the Sigel-Jones match. I doubt that it is the general publics familiarity of the game of 8 ball as most people also know 9 ball and nine ball would be the easiest game to explain the rules to someone new to pool. Also keep in mind that a slower cloth is used. I believe the intent was to create a format that yields a better balance to the match. (This is a guess only. I would be interested in knowing why 8 ball was selected as the game.)
