I am always amused how different OEMs can release equipment with ”similar“ technologies at the same time! Case and point...Cleveland RTX Zipcore wedges and now, Mizuno ES21 wedges. Both clubs main marketing strategy is moving the CG of the club away from the hosel and towards the center of the face. Now, they do it completely different ways, but they essentially accomplished the same goal. Now, with the newly released TaylorMade Spider FCG, this does come across as copying directly off another OEM’s homework! But, we‘ve seen many instances of similar tech at the same time....Callaway ERC Soft “Triple Track” and Sacks Parente Vernier Acuity...Callaway A.I. Flash Face, TM Twist Face, Cobra Infinity Face...even same names...Tour Edge Wingman Putter and Bushnell Wingman Speaker! I know patents and trademarks plays a role in this, but can OEMs not keep a secret? What are your thoughts? Is it coincidental, corporate espionage, OEM employees talking to much while having a beer, jumping on the bandwagon?
