The Westside BT Harp is a straight putter and approach disc. It is designed to withstand any type of condition. It's a very reliable approach disc that 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 this could be the only approach disc you need to carry as it can hold any arm speed and still hyzer. For slower arms it will be an overstable approach disc. PDGA approved.
