TaylorMade RBZ vs Callaway GBB

3D Model

I noticed massive size difference between the old Callaway Greatest Big Bertha and the newer TaylorMade RocketBallz drivers, so I decided to use my iPhone and STLMaker to scan each of them and get and measure their volumes in meshlab. It turns out the RBZ at 460cc is about 1.5x larger than the GBB at 290cc. It’s likely not the only reason I was hitting bad shots before, but a larger club head should definitely help!
