...any putter that gives you the most confidence to make putts

My favorite putter recommendation is any putter that gives you the most confidence to make putts. There is however a distinct physical advantage with any putter that is face balanced (mostly mallets) for off-center hits aren’t affected nearly as much. Lastly, I’ve learned someone who is a good putter is a good putter with any type of putter. So practice making putts!
