Faterson:
Many players actually prefer to putt while looking at the putt from reverse view.
I use both views, switching between the two, on every putt. I have been confused at times though when the break lines (the dots moving across the surface of the green) seem to appear different from one view to the other. Anyone else notice this? Or is it just my tired eyes?
I now trust the forward view more than the view from the cup back as, in my limited experience, it tends to give the better indication of the break.
