Penley ETA Wood 75 R Flex Shaft .350
The ETA (Energy Transfer Accelerance) shaft was designed to increase and maximize the transfer of energy of the shaft from the butt to tip end. Using hybrid proprietary materials combined with proper geometric shape and designed with TBAR.
The ETA’s tip section has an extremely high rate of recovery due to specific materials which causes it to have a high launch angle with a low spin rate. ETA means achieving more energy at impact which translates into more distance.
