I got to try the Pin Hacker, Exodus Solid and Exodus Pearl on the USBC Open Pattern in my home center. Our house uses Brunswick Anvilanes, with Twister pins and a Kegel Oiling Machine. I had the best look with the Pin Hacker on this pattern going straight up 7-8, there is a lot of backend as some reports were saying from their experiences so far at this years Open. Not sure how close our house is to the actual Open conditons as there are several variables even though the lanes are set-up the same way.
The Exodus Solid and Exodus Pearl both had good looks as well but the Pin Hacker was a clear favorite today. I was able to use the Exodus Pearl pretty much off the same line as the Pin Hacker whereas the Exodus Solid needed a moveleft with my feet to get the same results. Overall I played the lanes pretty much straight-up 7-8 with no missing inside as the ball would jump left at the end of the pattern, and none of the balls would recover consistently if missed wide(i.e. 5 board out to gutter).
I plan on testing them again in the coming 2 weeks before I go to bowl the Open and will report out shortly thereafter.
