I got this disc in a f2nd, 154gram.  It is one of the best forehand discs I have used.  It is very dependable in a tunnel shot for me.  I average about 325 to 375 with this disc in most conditions.  

I will say that this disc gets a bit unpredictable in a head wind but I have yet to throw it in a heavier plastic. 

I haven't had a chance to try one of these that are brand new, but I threw 2 broken in discs, and this review is based off of those. This disc is SO FLIPPY. I threw a total of 12 throws (6 throws with 2 different Blizzard C-Line DD2's), and didn't keep it in the air once. I would throw a super hyzer angle, and I would watch it flip up, start carrying to the right until it hit the ground. I watched that 12 times, a few of them I threw so high in the air, but still watched it pan out to the right. 

I would suggest this disc for someone with very low arm speed. It doesn't take a lot of power to keep this disc in the air, because clearly I had way too much power.
