The Westside BT Swan 1 Reborn is a stable to slightly understable disc golf putter and approach disc. It was Westside's original putter and it would fly straight for anyone right off the shelf. The Swan 1 was designed to give lower arm speeds a straighter putting line. BT Hard will give you that consistent fast release you get from stiffer plastics.
Speed 3, Glide 3, Turn -1, Fade 0.
Available in soft, medium and hard BT plastic, 173-176 grams
BT plastic has good grip, same flight characteristics as VIP and Tournament, less durability but is more economical. In opaque colors, BT may be available in Hard, Medium, Soft and Megasoft (stickiest best grip). BT plastic was formerly Eco1.
