While helping my father in-law clean out some of their basement, we came across two bowling balls, a Columbia Quake and a Brunswick Zone Speed Demon. Both balls are 16 lbs. and are in very good condition. Can anyone provide some info on either ball if you have one or have used either ball as to what lane conditions are they best used for, reaction...etc... I might want to have one or both plugged and re-drilled for myself. Any info anyone can provide would be appreciated.  Thanks.
