I don't see any reason to have the latest and greatest equipment either. Drivers moved from about 250cc to 460cc as standard sizes within 10 years or so. I was hung up on using a Cleveland Quadpro until 2 seasons ago. It's about 275cc and is a classic teardrop like the Titleist 975. I won't be getting rid of it anytime soon. If I ever need to find my tempo, it's back to this guy. It's pretty heavy.
TM turned a corner when they went from the old brown Burner to the 1st generation R series; R510, R540 and R580.
Equipment......it's all about what works for you. And the best thing you can do is to spend money on custom fitting everything.
