The Severe Delirium is the second release in this series that pairs the Resurgence core that was used in the Eruption line with a flavor of the Bend-It coverstock, which was used previously in the Vow and Omen. This ball’s Bend-It Hybrid cover is finished with a rough 2000 Abralon surface, making it match up most effectively on heavier volume patterns.

Two of our testers, Tweener and Stroker, liked this ball best on our heavy test pattern. For them, the Severe Delirium offered lots of traction in the front of the lane, giving them enough total hook to get to the pocket on this pattern. Cranker saw his ball want to start up a little early, but he could get the recovery he needed when he tried to open his angles and get it
