Latitude 64 says this about the Fuse: It has been co-designed with our pro Jesper Lundmark. We wanted a disc that could hold curves with minimal fade at the end and are really pleased with the outcome. This superb midrange will fit in most players bags and is available in our popular Opto and Gold Line plastics. The Fuse has a stable predictable flight pattern. Compared to our Core it has a shallower rim and is a little slower.
