What? They want to hit center-they don't need to. A too long a beater (or too short) will affect your speed and dexterity (I didn't see that comment). So trying to hit center may throw off their usual beater dexterity. Least that's my experience experimenting with beater length. I don't change my beater moving the pedal from my 16 in kick and my 24 in kick. My pedal is set for my pleasure not the bass drum pleasure. Just my two cents.
