When I began my foray as a fledgling recreational golfer back in 1990, PING was considered the standard as far as quality equipment (irons specifically). Some 28 years later - they're still more than relevant and holding their own.
They've refused to participate in the modern day club-of-the-month marketing scheme, and held steady during all this time since. Keep it simple, don't stray too far away from what has worked.
If they invented a 3-piece ball - I would undoubtedly be all-in, based on the quality of their product. But that's just it.... they don't want to be involved in the ball market. Keep producing a quality product with outstanding customer service and brand recognition within the confines of what they're known for.
Whether I play another 2-3 years or another 20-30 years - PING has earned my loyalty. And it doesn't exactly hurt my feelings that the clubs they manufactured 25+ years ago are just as good as anything else on the market today.
It might not be the greatest marketing ploy, but it does add credence to the respect and reputation of the product they produce.
