A player with a slower swing speed may have trouble elevating their long irons in a single length set. Without the swing speed required to achieve an adequate launch, it can sap the distance of their “long” irons. For many however, a lower launch on their long irons in single length clubs is worth the trade-off of having game improvement consistency.The Best of Both WorldsIntroducing the Pinhawk Vertex Dual Length Irons!
