This is a great disc. Fission special edition is way more domey and flippy than neutron trails. But both are good. 

Only 2 months in and I've been working on my driving consistency. The first round using this disc I birdied 4 holes at my local course. It doesn't feel like I need to put a lot of power into it to get it to fly straight or far, so it lets me focus on my form and get out of my head about how hard I need to throw. I haven't made it past the 400ft mark yet but I feel this is the disc I will do it with.

The only other discs I own that are MVP are the Entropy and the Axiom Crave and Paradox. I was excited when I saw the Fission Trail come out because I tend to throw lighter discs. Today when they were released, I bought a 148 gram Fission Trail and immediately took it out to the field. It was a bit windy, so I'm not certain whether or not my review will be accurate for the typical day, as I was having to manipulate the release angle in order to accommodate the wind.  All I can say at this point is that I'm immediately able to out throw any other disc in my bag with this Trail.
