This Dave Feldberg designed putt and approach disc is already making waves in the disc golf community. The Dagger is a stable putter that features a beaded rim and a deep flight plate intended to offer tons of glide. Dave Feldberg, a long time Innova pro, switched to Latitude 64 in 2013 and has been working closely with the company behind the scenes. This is just the first disc he has approved and co-designed. I would expect more to come in the future.
The Zero Line plastic is Latitude's entry level material. The "Medium" flex is in between the Zero Line Soft and Zero Line Hard flexes. The best of both worlds.
