The zinc aluminum ring provides extreme perimeter weighting for balance and feel. It also contributes to a smoother roll. more dramatic 3-ball aid (like the Pelz 3-ball putter 20 years ago). But the most striking change is the circular metal ring. It is designed to promote a smoother straight-backand- through stroke. It also means your mis-hits should hug their lines better. After you try it, you may want to hug the designer, too.
