In the fall of 1997, the band took some time off so that members could pursue education. In 1998, the band resumed touring, and was the opening band on the fall tour of the Deftones. A split EP was released in the summer of 1999 with Boy Sets Fire. These were the last recordings with bassist Bob Whiteside.

"Designs For Automation" was released in January 2000. They spent most of 2000 on tour, and performed on the Deconstruction tour in Europe with NOFX, played the main stage of the Vans Warped Tour in the summer. Ben Lythberg began playing drums for the band during the fall, winter and spring while Redmond finished his masters degree.
