I like it too...make you play early, middle and end stages of the game.
Plus, makes you feel manly when you run all the balls on the table.
I haven't gotten all 15 yet brochacho. I ran 12 and then 13 the next rack a couple days ago. That 13 was the first time. I rattled a bank trying to get behind a ball near his rail. I had a decent cut for all 15 had the bank gone.
One of these days 1P ..One of these days.
I suppose you could get all 15 in multiple innings as well and still feel super puff. Giving no scraps.
