Golfsmith Hi-COR Hybrid Head: This Golfsmith Hi-COR takes the original Hi-COR concept of placing more weight in the rear of the head and expands it with a unique shape and rearward crown step design. The large sole keeps the CG low, yet the sole radius provides good relief from the turf and places well from a variety of lie conditions. Like the Hi-COR fairways, the face is 15-7 steel at 2.2mm thickness. By crafting the face from 15-7 steel, mass can be placed in the rear portion of the body to provide a low, deep center of gravity (CG) optimal launch. These hybrids have slight offset to help with accuracy and reduce pushes and slices. .350" bore provides maximum stability at impact. Download HI-COR Hybrid Clubhead Specs (164 KB)
