The Westside BT Harp is a straight putter made with BT plastic (formerly Eco1). It is designed to withstand any type of conditions. It will hold in the wind. The BT Soft Harp is very flexible and feels great in your hand. Use the soft in cold weather and it will still have that soft feel. Use the BT Hard in the summer and it will still hold its shape. For professional players, it can hold anyone's arm speed and still hyzer. For slower arms, it will be an over stable approach disc. PDGA approved.
