I've had a few of the earlier balls and I'll rank my favorite in this order....
1. Original Break, cracked a long, long, time ago.
2. Blue/Blue HOOK, drilled Motion Hole. Still use it and love it!
3. Break Pearl, gave it to my son.
4. S-75, cracked a long, long, time ago, before the Original cracked.
5. Blue/Orange HOOK, only because this is the last 900 ball I purchased.
