Perhaps one of the major reasons for the decline isn't the balls, nor the easy scoring conditions.
The new style "Family Entertainment Centers" in my area are all booming with open play. Families schedule their kids birthday parties and local companies will have company sponsored events for their employees. Young people get together with their dates on Friday and Saturday night for "Glow Bowling" and drinks and generally have a fun time.
But the old school houses that are dumps with water stains on the acoustic ceiling tiles, stained/worn carpet, bathrooms that look like hell and smell like urine, an overall faint odor of stale grease/sweat and walls that are covered with cheesy looking banners from local advertising attempts to squeeze in a few more bucks.
But yea, it's the modern reactive balls and easy scoring conditions that are killing bowling.
