AutoFlex Golf Shaft from Dumina. A Korean Golf Company makes an amazing new golf shaft.

The AutoFlex Golf shaft from Dumina is pretty amazing. I tested the SF505X model and talk about results and if it needs to be FLO’d. The AutoFlex shafts provide higher swing speeds and ball speeds, but like all graphite golf shafts, they should be PURED or FLO’d. The AutoFlex shaft is very whippy at low speeds and less at high speeds…interesting. Dumina company says it’s behavior is due to Hidden Korean Technology? No one knows what that is. The company also will not release the specs of the shaft. Strange but cool.
