Yes, I know I acknowledged that in the first sentence of the post. I will butt out but thought this was more of an impactful aspect than distance.
Anyway I have nothing to add to the distance debate. Don't think there is enough to address.
I won't harp on this but I have spent a lifetime optimizing, NVH, directional and structural forces of dynamic engine components and environments so I can tell you you are a bit off on 'no effect' statement.
There is an effect of MOI on face-path-direction correction. In simpler terms gear effect is not eliminated by any means but is reduced.
Anyway, no need to respond unless you want to.
What launch monitors are you talking about and who told you that?
They are using Trackman for the launch characteristics they show on TV like ball speed, carry, etc. so yes some of the longer hitters can absolutely reach 345 yards and Trackman is one of the top end launch monitors that exists right now especially when used outside to track the entire ball flight so yes I'd say it is very accurate.
They should have a Northern Swing this time of year. Play indoor golf like the rest of us suckers.
I have been looking at irons all winter, but I have been told three times that the launch monitors are not that accurate. Here they are short, so are the one’s on TV long? Are they really hitting that Maverick 345 yards?
