I was practicing with a friends Valkyrie last night. If I remember right, it acts like my Leopard which used to curve left now banks hard right every time. I hate it. They say they "break in" and fly differently but I don't know how thats possible. It could be that I'm throwing it harder with more spin and that changed it flight characteristics. I used an old Discraft XL that my friend found and that flys straight as an arrow. Also tried an Innova Orc which curves HARD left but it got me out of a tricky area today. For the shorter throws, my Innova Shark is pretty predictable. I have 3 discs now but I need more.
