Kevin, this is the putter that I personally use. Yes, it is perfectly U.S.G.A. legal and yes you can stand it up and walk all around it when lining up your putt. One thing is for sure; you will be noticed when you putt with it. I like to stand it up on the practice putting green and walk away from it and watch everybody stare at it. Kevin, this putter still holds the record for the highest moment of inertia putter ever made and marketed. Here is some more fun to prove MOI to your friends and yourself; line up your putt with the ball way out on the toe of the putter and stroke it. You will be amazed at how solid it feels and the ball rolls just like normal and with almost no distance loss like most other putters (high MOI does this). Final trick; put down two balls to be putted with one stroke. Leave 3/4” to 1” between them and line them up with the hole so that you will impact both of them at the same time (one on the toe and one on the heel). If you are lined up properly, both balls will head toward the hole in a lead/follow arrangement and both will go in the hole. Use about a 10 to 15 foot putt distance. I have also made three balls doing this but it takes a number of tries. I usually make the two balls every 4th or 5th try if it’s my lucky day. Thanks for trying Maltby designed products.
