A pendulum can work well if you can get very low. When age or injury forces a higher stance it becomes impossible to "lock" a shoulder since it can't be locked anyway. Soft tissue at maximum extension can make it feel locked to some degree. As soon as you can't get maximum extension on the soft tissue, no more shoulder "lock".

I have never liked a pendulum because it is an unnatural movement that is very rarely used except when shooting pool. A full arm movement is used every time we walk.

Tried this out in the pool hall and it was well received. Everyone liked it so far. The beeps are not annoying at all, compared to how echoey they were in my garage.

He's a good player. The last good one to come out of Philly. I think he's about 25 now and lives in Mississippi. I knew him well when he was coming up in Philly around age 14. His dad is real good too.
