I saw a staffer throw one last night. I believe your instincts are correct. We were playing on medium oil, although all our practice shots gave the illusion of there being more oil out there, than normal. It wasn't..... just backends that hadn't been cleaned properly.
He started well on the fresh, a double then 9/. After that, with 9 other righthanders playing a similar line, ball began to check up badly.
He actually had better success, playing right of everyone else!!! But I truly believe it was just a bad ball choice on our conditions. Cool thing about this ball.....once it sets up, it tends to drive the pins backwards, from what I've seen.
