The ferrule could be loose or cracked (inside). I have fixed a bunch for that. I haven't seen the shaft yet, but I had someone call me last week because there is something loose inside the shaft.

FusionCue now allows you to provide an overhead view screenshot of an existing ball layout, and it will extract the precise location of every ball and allow you to run them out -- fully equipped with stats, optional landing zones, etc..
Perfect for "What I would do?" scenarios, or for just learning.
