If you're a former anchor putter and you're finding that counter-balanced solutions aren't effective and aren't heavy enough to prevent twitching and pulling putts, then you should look at the L2.

While it is easy to be hung up on the size, it does back up the performance characteristics which it touts.

I feel that the L2 Traditional putter is a very good putter with some very strong design characteristics that make it an interesting putter.

A consistent smooth, pendulum tempo is the greatest asset of the Lateral Line putting stroke. The same tempo that only varies in length to determine distance gives a golfer a yip-proof motion.

The Sand Trap

I love Johns putter, but I love the putting system even more.

It’s the heaviest putter I’ve ever tested and comes with a disclaimer: “This putter is not for everyone, only those players who wish to improve their overall putting skills.’’

As advertised the L2 is forgiving, perhaps the most forgiving we have ever tested though admittedly that’s a subjective judgment. What is without question though, if you are having problems making solid contact, beset by the “twitches” or still looking for a replacement for your banned belly or broomstick there could be some distinct benefits from this putter.

Enter science and a new trend in putting technology. The physics-inspired L2 MOI MAXX putter incorporates size and weight into a perimeter weighted design engineered for one purpose – to make putting more simple and to lower scores.

Yes it's way too big. Yes it's way too heavy. Yes it doesn't look like a Scotty, a Bettinardi, or even an Odyssey for that matter, but for those who are searching for an answer to the new USGA anchoring ban, or are just struggling to make a consistent stroke, John Ambrose might have created your solution.
