When I first started throwing the Avenger (RHBH), I found the disc to be a little overstable for me, but I hadn't been playing too long. I still threw it a lot and really enjoyed it. Everyone wants to always compare discs flight characteristics, but I find it hard to compare it to another discs as we all throw differently. From my experience, it doesn't have as much high speed turn as much as my 175g Champion Teebird (when I throw mine flat, it turns), but will fade at the end of it's flight similar. If I had to compare it to another discs, I would say an Orc. The Avenger always had a priority in my bag, but once this disc got beat it, it was a staple in my bag for all woods shots. For me, I always threw this disc RHBH. If I tried to forehand this discs, it would turn over. I also used this discs for thumber shots around 200ft. Again, with any discs, let it beat in. I kept throwing it for months, knocked it around on some trees, and it became my woods driver that I wasn't afriad to smash a tree with it. It took over a year, but this discs became a very, very straight driver for me. Once it was nice and beat in, when throwing 250+ I would release on a small hyzer and let it flip up and just fly straight. If I released flat, I could produce a beautiful S-curve that I loved watching. I could put release on an anhyzer and it would hold almost the entire way. 

this disc is a lil to overstable for me but its still a great disc once you can get you're arm speed right you can get the disc to flip up and have a nice little s flight before it fades back left I prefer the avenger ss but I am just a recreational and my power isn't  at it top performance in closing the avenger is a great disc for more advance players

If I had to pick three discs to use for a round it would be this one, my "wizard" putter, and my "zone" approach putter. My bag wouldn't be the same without this disc. I can always rely on this disc to give me absolutely zero turn. I would not get this though if you have a weak arm or you are learning the sport. But if you master this disc it will produce the same results 100% of the time.

p.s. I like the FLX plastic but i am dieing to try it in Z plastic or ESP
