I can’t speak for others or a general view but my experiance is it makes a world of difference along with the head.
I was previously fitted for a 10.5 degree Sim Max with a stiff Adila rogue shaft. Carrying around 240 yards due to the spin.
Latest fitting at Scottsdale I ended up with a x stiff motore shaft in a 8 degree sim2 (non max) head now carrying 285 and spinning 2K
Ball flight and distance is night and day. And as mentioned I was actually fitted for the first one so I’d imagine if your current driver wasn’t fitted there could be massive games to be head. But saying that the current driver your using could suit you so hard to say what your experience will be.
