I want to preface this with I love this disc and enjoy it a lot. 
 

Plastic: X Out Halo S-Blend 

I believe that this disc is a great disc as long as you know how to use it. But I feel the same for any disc in the Firebird slot. Either your throwing it on forehand or backhand. The disc is very workable and isn't just a beef cake. I was able to get good distance on it throwing it on slight anhyzer. 

The halo plastic is by far one of my favorites is always looks great feels great and flys great.

Dont recommend this for most players as its lower glide and over stability can be very hard to work with without proper angle control and arm speed.

I love it! When I throw forehand I need something super overstable, this is that disc. If you like the Firebird, but feel like it's not perfect then try this bad boy out. The "4" glide made it more favorable for me compared to the Firebird. And if you're  wondering about the "4" fade, it's legit.

Instantly my favorite new disc in a while.  Looking at the rim, its Identical to a firebird and flies like it.  The 2nd round I ever took this out was on a par 3 course with a lot of 200'-300' holes, I had 4 or 5 near-aces and the only reason one didn't go in is because it was a church course and I have sinned.  Super beefy, super reliable, flex-lines, forehands, headwind, the Scepter is good.
