Do normal golf shops (edwinn watts, golf galaxy, etc) have the same custom fitting tools or would a trip to a Ping performance center be required?
Most shops have the basic fitting cart with a handful of shafts and usually 35% of the shafts are regular flex, 55% are stiff flex and the remaining 10% are X Flex.
From my time perusing various golf shops, here's what you can find and price point:
Basic Fitting Cart:
Golf Galaxy or Edwin Watts - Free
Public area of PGA SS - Free
Advanced shaft selection:
Fitting area of PGA SS - $
Golf Courses with Ping affiliation - $
Best selection available to the public:
Club Champion - $$
Ping HQ - $$$$
Call your PGA SS and ask for the fitting area. The one here in The Woodlands has a really good selection of shafts for various companies. The majority of the shafts are for TM and Callaway, but there's still a good selection for Cobra and Ping...depending on if the company has updated their adapter. I did a driver fitting for $49 at the SS and went through 14 different club/shaft combos before settling on one I liked.
TaylorMade '17 M2 w/ Aldila Tour Green 75 TX Stiff
Cobra F7+ 3W 14.5* w/ Aldila Tour Green 75X tipped 1/2"
Callaway X2 Hot Pro 18* hybrid w/ Aldila Tour Green 75 X
Callaway Apex Hybrid 20* w/ Hzrdus Black 85 6.5
Bridgestone JCB15 4-PW irons w/ KBS C-Taper S+
Callaway MD Forged 52* w/ DG Tour S400
Callaway MD3 58* C Grind w/ DG Wedge Flex
Ping Vault 2.0 Stealth Dale Anser w/ tungsten weights (365g head weight)
All my clubs are lefty style...cause I thoroughly enjoy having limited options when buying golf equipment.
