I tied the Modus 3, never figured out what the hype is either.
Oddly enough though, I see huge differences in driver and wood shafts, irons don’t seem to change all that much in the real world results, assuming they are relatively close to fitting me. It’s graphite for me, due to elbow issues, but I can’t really say there is a huge difference between my Steelfiber 125s and the Matrix Kujoh 95x I started using. Kujoh is slightly softer feeling, there is a balance point difference, but results really don’t change.
