Is there a big mistake that you see with amateur golfers yeah that's a great question I would say putter fitting like is important like the length of the putter the weights of the putter. So you would rarely go buy a driver now without testing it right you would never get a set of irons without hitting balls and making sure you have right lengths weights so many members don't have a putter that's the right length they have no idea the concept of what weight is Swing weight total weight no concept of the stroke.
