Cobra Tricep Putter: Banned or not?

Some years ago (1.995 or so) King Cobra launched a revolutionary putter called Tricep. I got it as a premium piece of golf innovation and enjoyed it specially in lag putts. At first, I was happy no one had it as a touch of exclusivity, but as years go by and never have seen one in all my life, it is turning a touch of eccentricity.

It works planting the shaft in the outer side of your left armpit (the tricep muscle). As it is not anchored in the chest, but in your arm, a la Kuchar style, the question is whether its use is banned under the new rule in 2016.

What do you think?

Eccentric

The club is fine.  Use it all you want.  Having the club in contact with your body above the elbow isn't allowed as I understand it.  Kuchar only runs it up his forearm.

It isn't the putter which would be disallowed, only the method with which it might be used.  If your method of anchoring it in your triceps also includes locking the upper arm to the body creating an anchored pivot, then I'm thinking that it would not be permitted.  That would amount to moving the pivot point a couple of inches but not effectively changing anything from the standard broomstick position against the chest.  The whole point of the rule change is to require that the part of the body controlling the club (the hands and forearms) not be anchored to the torso, so that the player makes a conventional stroke rather than a hinged pivot.  Locking the upper arm to the torso, then anchoring the club against that would be seen as trying to circumvent the rule without actually changing your stroke.

This is of course my opinion based on how you described your stroke.  Not seeing what you actually do, I can't be certain of anything.
