THE SKINNY ON THE LATEST AND GREATEST


52 Hook 15 Length 15 Breakpoint Shape COLUMBIA 300: DELIRIUM


Manufacturer’s Intent: “The Delirium combines two proven winners in the Bend-It pearl cover and Resurgence core,” says EBI’s Bugsy Kelly. “The low RG core design offers a fast-revving ball motion with easy length and a strong backend, which is attributed to the Bend-It pearl cover. Whether you were a fan of the Eruption [July 2011] or the Vow [February 2013], this new release will bring out the fanatic in you. The Delirium is best suited for medium to oily lane conditions.”


Core: The famous Resurgence core, used in sev- eral other Columbia winners, has an RG of 2.46 and a .043 differential.


Coverstock: The cool purple flair Bend-It pearl coverstock is sanded with 500 and 1000 Abralon and polished with Powerhouse Factory Finish. We


measured an RA value of 3.38 with an effective surface grit of 4470.


Overview: The Delirium is for medium to oily lanes, but it is still clean enough for when the lanes start to transition. It’s a good number two or three ball in your arsenal once the patterns open up or the fronts start to go. It gave us a good look on the longer Stone Street pattern, playing more direct up the track area on the fresh. The pearl cover did not make the breakpoint too late. On the USBC Doubles/Singles pattern, we saw the ball come off the pattern stronger and with more angle. On the fresh, we tried to keep our hand behind the ball to control the back-end motion, but when the pattern developed, we could get around it and open up the lane. On our lighter house pattern, we could get in around 17 at the

arrows and open the pattern up to the track area with a tighter line and a strong carry percentage. Those with high rev rates will see length and no overreaction on the backend when the pattern starts to go or when bowling on lighter volume patterns. Players with lower ball speeds can play a more down-and-in shot with added length and a strong roll and back-end motion. The Delirium is earlier and about four boards more hook with our feet than the Eruption Pro Hybrid (October 2014), and at least eight more than the Deep Freeze (reviewed this month).
