I need to replace the stiff shafts in my Ping i15 irons with regular or senior shafts – do these require taper tip shafts?
Yes they do. Ping Irons use taper tip shafts as it’s one less cut they have to do when they assemble them.
you can also ream the pings out to accept .370″. I’ve done this often for quite a few ping owners.
The Ping i15 do take .355″ taper tip shafts.
