I wanted to review this plastic specifically because it changes everything about the fierce. The Z metallic fierces are the most stable run I've found of fierces and they fly great. If you throw it hard with a touch of hyzer it will flip up but not turn too much, and thrown flat it will turn but have enough late stability to end up being a really straight flight. My favorite throws with this disc and the main throws I use it for are big turnovers backhand or forehand. It is so good with that flight and holds the line and slowly pans out, it never fades out early and never turns over. Excellent run of fierces 

Summary: Great for everyone, just might not feel like it's for everyone.

Feel: The Z Metallic plastic is everything you'd want for a premium plastic. It has all the firmness for confidence in the throw, but enough grip for confidence in the hand. TheFierce feels like if you took a Luna and just extended to top. It's fairly deep, which is really a preferance that you can make your own opinion on. 

Flight: I believe the slow speed of the disc makes the understability a tad less than the numbers would suggest. It'll for sure flip up, but it isn't a disc that will burn over and be useless for throwing. 

The flight of the tour series fierce is amazing. It holds most lines that you put it on, but does not flip over very hard when thrown on full power. It can glide forever, but just be sure that it is thrown in the right direction haha. I will warn that the rim is very rounded and the metallic z plastic can be slippery when brand new. Overall, great driving and upshot disc if thrown correctly.
