Just picked up my first cue made by Mezz. It's a predator cue and is signed by K. Miki.... Is there any difference between these cues that are signed vs the rest of the manufacturer cues? (besides the signature of course)... Meaning, do the people signing the cue have anymore time invested with that cue, or built by the signer, or oversee the production of that cue? Or is just a signature?
