However, I was unsure about the whole “Constant Weight” thing in the taper tip models, but let me tell you, it’s legit. Every club in my set felt right, no matter the length. They were all in sync, ready to tackle whatever the course threw.

Also, the steel fibers were integrated into the graphite – a genius move. It brought this unique blend of flex, geometry, and straightness that I hadn’t experienced before.

My swing was noticeably more controlled due to the low torque. It was like upgrading from a regular TV to a 4K – you didn’t know what you were missing until you tried it.

I noticed an improvement in distance without feeling like my irons were launching into space. It was that perfect balance where I could add some yards to my shots without compromising accuracy. In a way, the i95 understands my golfing needs and delivers.
