I will start off saying that this disc is terrible for most backhand shots.  It wants to turn on its side and fall out of the sky.  When thrown on a roller angle, it fights out completely and still ends on a hyzer.  Absolute wild disc and not much use throwing it that way.

This disc is the BEST thumber disc I have ever thrown.  I have tried all of the others, the XXX, the Firebird, the Felon, the MVP Shock (an old favourite of mine), and the TSA Omen (very similar disc, and offers a very similar shot), and many others.

I am a primary backhand thrower with no forehand, and this disc has allowed me to get similar shot placemts without throwing a forehand.  It can have huge air shots where it has a full flex flight before a reliable fade/drop.  It is great for thumber skip shots, which is a staple in my bag.  Thrown low and almost flat it can have a bit of flex before it hits the ground and has a great flare skip, great for getting around corners. 

This is one of the few discs I throw that I will never take out of my bag.  An absolute workhorse and bomber disc for thumbers.  

Utility/wind fighter for sure. Can guarantee will not hold a line, it just wants to dump into hyzer. It's a firebird but very flat with less glide and more dump. Would bag on windy days, else I have no use for it because it's normally unthrowable without making every shot a full flex, spike hyzer or flare skip. Not my style but it will return to the bag a few windy days per year.
