The Westside Harp is one of the most well known approach discs on the market. If you are a forehand approach player, you are missing out if you do not have one in your bag. The BT plastics allow the harp to slowly beat in so that eventually you can have a straight approach disc that still holds up to the wind out on the course.
When the wind is up and you need an overstable approach disc, look no further than the Anvil. The Anvil has good speed for a midrange with even more overstability than the Bard. If turning isn't an option, reach for the Anvil.
