re: Should I dial down the loft on my driver? Numbers inside

Those spin numbers are optimal. I wouldn’t change a thing if you are already accurate.

If go down in loft you’ll start getting those low knuckleballs that hook way OB. Sure every now and then, you’ll get the 1600rpm straight ball that carries 320, but your dispersion is gonna suffer.

Are you fitted for your irons? You should carry a 7-iron 170-180 with that swing speed.

That launch angle is a shaft issue and not a loft issue IMO.
