It wouldn't hurt to have something similar to say the avalanche series of Brunswick in terms of a medium core and a mild cover. I love my avalanche pearl when the lanes get a little dry/jumpy and the 505 is still too much.
But most staff guys can drill a couple of everything and easily have a 5 series to go much longer then anything else and be controllable on the backends. If he is still going to the KP it is because its a great ball he likes not that he couldn't drill something else to match it. (if i were guessing)
