Thoughts on drivers? | Golf Monthly

I'm not massive on big differences between good quality shafts, but I have noticed a difference between the Rogue in my 2017 M2 3W and the "updated" Rogue in my new Sim Max 3W. I'm happy to accept that it could be the same shaft with a different paint job and it could just be the 10grammes extra weight along with the newer head gives it a little extra umph, but certainly from a 2015 club, I think you'll see very noticeable differences with a new shaft and head.
If not, go protein shake and Donnay.
