Typhoon Using the same shaft, loft and any other settings you usually won’t find any difference from one year to the next.
Not necessarily so. I have several of the same shafts, specs as close as I could get. Cobra tips, Callaway tips, mainly. I do change tips if I try a TM, Ping, Titleist, or even Srixon.
Heads will play differently in some respects. Feel & sound will also be different a lot of times. Distances......maybe eke out a few more yards with some, over just last year's.
Some may even be easier to hit center, using same shafts, over last season. This is huge diff for some and will add yardage. Also might have changed aerodynamics that allow a bit faster swing.
There can be differences over last year's😉. And who won't take 5-10 more(possible) yards? That's a whole club diff from the FW to green, for a lot of us.
