From '76 to early-mid '90's Meucci cues were in the hands of more winners than all the rest combined. Buddy,Earl,Rempe,Sigel,Howard,Matlock,Efren and the list goes on.
Louie Roberts, Larry Hubbard, Breedlove. Yes the list goes on and on.
I would agree Meucci because now the players cues are spread out among a lot of different cuemakers.
Maybe if you wanted to get picky and say - Predator shafts - cause that was the first, if not one of the first, non deflection shafts - that everyone used on whatever cue maker butt they were using. That might beat out Meucci.
