ok so I have been fooling around with an old putter and a belly putter with the iPing app, I found that using the belly putter as a "training aid" (taking 10-15 strokes with the belly and then the 5 with the standard putter) increases consistency and helps with keeping the butt end of the standard putter pointed at the belly. Some of you may be like "Well Daa!", but i think that even if the PGA decides to ban the anchored putters, they can still be used to improve the stroke with a standard putter, being used as a training aid.
I am unable to find the article now, but on @GolfTips.com, there was an article about how keeping the butt end of your standard putter and using the same muscles to make the stroke as you would with a belly putter, result in much better consistency and performance.
