I was on a quest to replace my Prodigy A2 (350G Plastic) super-overstable workhorse that got too beat in, so I picked up a new A2 in 350G (that didn't fly how it should) and the Cosmic Neutron Entropy to compare. Having just become a full-fledged "Gyronaut" I couldn't help myself. The Cosmic Neutron Entropy looks and feels feels great, and I throw it backhand pretty well, but I'm so used to and reliant upon the A2's predictable flight and comfortable feel for both forehand and backhand in my hand that I bought an additional A2 (750G Plastic) that flies great. So now the Entropy is a cool disc without a starting spot in my bag (hence the title). Nothing wrong with it, the Entropy serves a very similar role as the A2, Zone, and other meathook utility approach discs, it just has a little different shape and feel than the A2 that I know and love.
