I tried to go from a Ping Anser to a face balanced putter a few years ago. That was a big failure. I like to putt with forward press. A face balanced putter will then flip open in the back swing and flip closed in the follow thru. So I had big problems keeping the club face stable through impact. But it depends on your stroke. If you simply let the putter hand down from your hands and swing it from there it probably works OK. Also, you get a bigger sweet spot and perhaps a nice gear effect when the COG is far behind the club face.

A Ping Anser type of putter is very different. It has a more neutral weight distribution and is also much lighter overall, so you can basically use it as an extension of your hands.

Someone ought to make a 360* balanced putter - one that didn't have any face angle bias at all but left everything to the player's hands. A putter where the moi center, the cog center and the sweet spot were all in the same point. Then the clubface would obey your hands without resistance regardless of your stroke.
