There are 3 facts people generally seem to ignore regarding strong hooking, oil loving balls:
1. They absorb oil like sponges. They need to be cleaned IMMEDIATELY after use, with a strong, GOOD, deep cleaner. They may need/require oil extraction more often than less strong balls.
2. All balls today are subject to having their surface changed by use, in proportion to the surface on which they are used, their original surface and the rev rate of the user. You may need to restore/refresh the surface as often as every 10 - 15 games!
3. These strong balls requires heavy oil to get them to perform properly and to retain enough of the energy applied by the release (rev rate, ball speed, tilt, rotation, surface, etc.) to discharge that energy at the pins when it reaches the pocket/pins. If the user is not playing then proper part of the lane for the release/drilling/surface/ball design, especially for these super strong balls (Reax, Sync, Defiant, Paranormal, Nightmare, whatever) They're going to look like they died.
99.9% of the time, if they look they died, look to one of the above causes. Otherwise, look in the mirror.
