I always find Discraft very interesting. Unfortunately, their 21 mm to 22mm rimmed discs, the Surge and the Surge SS don't work well for me. On the other hand, I will put their consistency against anyone else. Years of buying Innova has shown me that about one in five discs is an anomaly. It flies way off the standard for the disc in question, taking into account the disc type and plastic. This doesn't seem to happen for Discraft. If they say a disc is .5 in such and such plastic, it is .5 no matter how many I buy. I use Buzzes as my mids, and every one flies exactly how advertised. When I tried out Surges, I bought thirty of them, and everyone flew the same as the one before. Even more, if you look at their discs off the shelf, they all seem flat. By that, I don't think I've ever found a "domey" Discraft disc.
The downside is that I can't get the discs I want in the plastic I want. Innova is spotty on their plastics too, but they have the discs I want in the plastic I want, for the most part. If Discraft widened their plastic choices on their fairway drivers, both long and short, I'd be much more willing to commit to a wider range of their discs.
No matter how you slice it, they are doing something right, at least for what I see.
