<<Biased (former) player alert!>>
I am uncomfortable with changing a rule affecting such an important
part success in tournament golf. There are players who switched,
learned, and built success, within the framework of the rules.
Now, these players may be told, sorry, you worked to become proficient at this,
but you are going to have to relearn the portion of the game that impacts success more than any other.
Of course an argument can be made that this is a big reason TO change the rule, because it is so important.
I use a 31" putter, so no dog in the fight. But if someone has learned to use a long or belly putter
through their development, it be like telling me to putt left handed. I could learn it, but the carnage would
be significant.
