Is low deflection something that you really want, especially after years of maple shafts? Do players actually see their game improve with ld play? I am a 500 fargo player and I can alternate between wood and cf easily, without me noticing much. I actually think I prefer wood for feedback.
Like most things I think it's a compromise and only you can decide if it's worth the effort to retrain your brain for a LD shaft.
In my opinion low deflection can help mask some imperfections in a stroke. If you strike the ball slightly off from where you intended the results are not as dramatic as it would have been with a higher deflection shaft.
I personally find it difficult to masse or swerve with a LD shaft. Not really sure if that's just me or if it is because of the shafts, but it seems to be a thing.
For whatever it's worth, I know Oscar Domingez has said publicly that the reason he plays with the 12.9 Infuzed is because it has more deflection than the smaller shafts and he feels like he needs that.
