i currently use a columbia resurgence, hammer black widow solid, and a twisted that i polished for dryer lanes. i wanted something between my widow and twisted. i was thinking about the ultra zone but a close friend of mine told me the rival is a great ball as well for this lane condition. i want something that will be very controllable. i was wondering what your thoughts were. thanks.
(i know i posted a topic about the ultra zone before, im just looking for a comparison to the rival because ive heard great things about that ball too. thanks)
