Love the disc in Star plastic. I wanted a backup to my main Star Valk but in a heavier weight. After throwing the disc and taking a closer look/feel at the plastic, I noticed I was sent G-Star plastic. Still a great disc, but G-Star and Star fly differently and it is not what I was looking for. Very disappointed since Infinite is usually spot on. 

Great disc. Nothing is really special about them but they  glide a ton, they go far, and ride whatever line you put them on. If you want a disc to fill in that beat Thunderbird slot, this disc is is. 
I have bagged Valk's, Escapes, and TI Heats. Loving my Valk the most now but they are all interchangeable. 

I think the name says it all as one of the most popular drivers. I love it. As it beats in it has very reliable turn, I'd even call it understable. Off the shelf, it is a pretty straight to left shooter. I have this disc in various plastics and stages and always keep at least one in my bag. There is always a spot that the Valk can fill. For me currently, I use my most understable champion as my go to forehand driver. My forehand isn't the best, but I can get 200 feet straight on a hyzer flip. A little more if I keep it flat and can let the disc work to flex out and back.

When I started playing I didn't have the arm speed to throw backhand. Every drive and upshot was forehand and this disc was my go to. Now a year later things have improved and the valkyrie has remained one of my favorite discs. I carry two in my bag in different weights, always Star or GStar plastic.
