The Swan 1 was Westside’s original putter and it would fly straight for anyone right of the shelf. The Swan 2 has the exact same feel as a Swan 1 with a better flight. The Swan 2 holds the line a little better and can be used in the wind with success. The Swan 1 was designed to give lower arm speeds a straighter putting line, the Swan 2 will give all players that long straight putt they have been looking for on the course.
