PING ALTA DISTANZA 40g Shaft with adjustable features, customizable. - Model: ALTA DISTANZA 40 - Brand: PING - Adjustment: +1.0 / -1.0 Thank you for viewing. I was using this with a G425-5W. It started to feel soft, so I switched to an S shaft and am selling this one. There is no S/R indication on the shaft itself, but the golf shop staff from whom I purchased it explained that it is a "soft shaft that flies well."
