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.
About BT Plastic:
Westside BT plastic has great flight characteristics, exactly as good as VIP and Tournament plastics. A novice player may feel the BT plastic easier to grip than our other plastics. The BT plastic is more economical compared to high-end VIP and Tournament plastics, but BT plastics durability is not as good.
