I was surprised none of them rolled out given their early-rolling nature PLUS the short oil.  Last year, we had a lot of Absolute Infernos, and Amletto was playing a much, much bigger hook than even Barnes was playing.

SH

Pro-Anvilane ( hardest lane surface )
Brunswick Oil ( very slick oil )
Brunswick Lane Machine ( oils each individual board )
High volume of oil up front
Higher ball speeds

These are some of the reasons why you saw more aggressive equipment on the shorter pattern. Plus remember that if you use weaker equipment that may be stronger down lane, the ball comes off the back of the pattern sideways and can be very uncontrollable
