The Tensei Orange CK 60 is the shaft I chose with my G425 from Ping. Wanted the AV Raw, but can't get that one from Ping now. Ping guy said it's a 'made for' so probably a watered down version of the aftermarket one. I prefer a shaft weight in the 50's range myself, but it wasn't an option in the CK from Ping.
The shaft seems to work fine for me. I don't like tip stiff shafts and I'd say the one in my Ping is not tip stiff. I'd say more medium if I had to guess. Easy for me to turn it over to hit a draw when I want.
