I hear you Dave. Over the years doing BGA stuff, I developed a very calibrated index finger and thumb. The whole thing about these devices and their balls, has always facinated me. Earl on, I began using my talented digits attempting to dislodge the little bastards. I know what it takes, and for all the other balls on these crap devices, they pass my test. They adhere very well. It's after they're soldered when most of the problems, besides as received, occur.
