Watt is a glidey, near straight putter and approach disc. Lots of glide for how slow it is, minimal fade, and it holds angles cleanly. Good disc for learning angle control since it shows you exactly what you did.

Neutron is the flagship and the one most people start with. Opaque, durable, and available in the widest range of bright colors, with a clean slightly firm feel and solid grip. It's the most true-to-numbers plastic in the lineup, meaning a new Neutron disc flies exactly like the mold says it should. The dense overmold also means it beats in slowly, so if you lose one and buy a replacement, the new disc flies like the old one did. Stiffens up in cold weather and picks up some flex and grip when it's hot without ever getting floppy.
