I was hitting balls last night with my son's 9i and 8i with Ping I20 CFS stiff shafts.
The 8i flight seemed okay, but a little high and short.
Then when I hit the 9i the ball would go out for a bit then appear to drop right out of the sky like it was thrown down. The distance seems a little short, but reasonable. I tried it again with another ball thinking the first one was a "limited flight" ball. Same thing. I took out one of the Titleist balls from the bucket (yes, we often have contributions), and same thing. The balls went out high and slowed down then dropped dead. No roll at all.
The normal flight of my Mizuno MP-52 DG S300 is a "parabolic" (I don't actually know). It seems like the time going up and the time going down are about the same and I get some roll.
Whereas it appears that the time going up with the pings is about 3.5:1. 3.5 counts up and 1 count down. My son was like "What???"
What do you think is happening?
