That Perez cue actually looks like it has a bumper? 
Anyway....as a clue, back in the old days....early 20th century....bumpers were called "noise subduers".
Bigger bumper = more vibration dampening.....smaller bumper = less dampening, no bumper = no dampening......some would say a more "crisp" hit?
