The Swan 2 is built on the same frame as the original Westside putter - the Swan (duh). It has the exact same feel as a Swan but a better flight line. It will hold a line a little better and can be used in the wind with success. The original Swan was designed to give lower arm speeds a straighter putting line, but this newer version can give all players that long straight putt they have been looking for on the course.
Originating out of FInland, Westside is now owned by Latitude 64 and Dynamic Discs. But they still continue to pump out a full lineup of discs.
While they are mainly known for their quality high speed drivers they still have discs suitable for, well, players like us including the popular Harp putt & approach disc.
