I'd love to know who and what that was. At the national level there's no device made
available or no tip standard or criteria for a cue/cue tip to be legal in certain circumstances.
Does anyone know what this device may have been?
I'll try to find the video and a picture I took after the match. You won't see much in the video besides 8 minutes of heehawing around which caused us to go to double points early, but I also snapped a picture of my tip after the match because they took a visible piece out of it.
