Westside's second putter in their growing line is the new Harp. The Harp will compliment the increasingly popular Swan 2. The Harp is more overstable than the Swan 2 which means it will handle headwinds better as well as higher speeds. The flight plate is flat and feels great for driving or putting. BT plastic comes in "Soft", "Medium", and "Hard" flexes so you can get what suits your hand the best. This line is SUPER grippy and feels great in the hand.
