3/4/0/1  *Limited run of TSA Ronin stamped Phi!  Storage wear possible with this plastic type.      

The Phi is a beadless putter that has less fade than the Penrose, providing a stable enough putter to handle headwinds and handle those approach shots with excellent glide. This makes for a great driving putter and a dependable putting putter.

OG Firm is the stiffest of the OG plastics with very little flexibility while still maintaining a good feel and grip.
