What Westside say:
The Harp is Westside's most reliable approach disc. Designed to withstand any type of conditions. It will hold in the wind. In BT Soft plastic the 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 stiff in the summer and it will still hold its shape. For professional players this could be there only approach disc they will need to carry as it can hold anyone's arm speed and still hyzer. For slower arms it will be your most over stable approach disc.

Harp (BT Soft)
This is world champion Ricky Wysocki's not-so-secret weapon for almost all his upshots. The super overstable nature of the flight, the super easy release with the rounded rim, and the low glide make this disc pin-point accurate in virtually every kind of condition.
The Harp, the Sinus and the Bard are all in the same family of very-overstable discs with low glide, and this makes them all easy to range.
