Cranker had the best look out of the three testers on the medium oil house shot pattern. His higher rev rate gave him a little more angle and back end reaction on this pattern compared to the other two testers, slightly edging them out for pin carry.

Cranker really liked how easily this shell cleared the front of the lane and how the carry continued to be good in transition, despite the relatively smooth shape.
