I'm posting this for a friend. He's selling his barely 2 game old Aura Paranormal. He is a 2 finger bowler, so the thumb specs or span I don't have any exact info. I want to say that it is probably close to 4 3/8. The fingers are vacu grip drilled. He saw a Brunswick Meanstreak and Meanstreak Brawler that he really wants and much rather have, than this strong ball in the Paranormal. We don't have much oil around here and he can't do anything with that Paranormal. He is asking $120 + actual shipping OBO....but he's seriously trying to recoup the majority of his money for a ball that hardly even touched the lanes.
