| (center of gravity) that is low and well back of | | | | shafted club. |

| This high MOI produces forgiveness on putts not | | | | technology features and materials described |
| hit exactly on the sweet spot, and the low and | | | | above but has a different head shape. Still a mallet |
| back CG means that the ball will skid less and get | | | | looking putter because of the weight bar running |
