There is a difference in grips, the heavier Nike having the MCC plus 4. Don’t know how many wraps and the Ping is a single wrap tour velvet.
j would say the Nike heads are heavier.
The machine is dead on...it’s a GC2 quad. The distance and ball flight are what I hit it. It’s the same outside. I went from the Pings to the Nikes and saw the same distance. Only thing I liked about the Nikes was a consistent draw. The lite shaft in the Pings have me some high and rights. I’ve learned a little too and thought going back to the Pings with the correction might yield more distance because of the weight difference but no.
Just odd.... seems like with me I adjust to whatever is in my hands. I was hitting another guys p790 modus 130 which should be high launch low spin and I was doing the opposite... low launch, mid spin.
