I drilled a Pyro up 2 days ago and threw it in league last night for the first time. I used it in games 2 and 3 shooting 235 and 248 (not bad considering I had no real idea what kind of reaction to expect). After league I used it in practice and shot 278 (left a solid 9 pin).
This ball goes very long, is very smooth and then, much like the Hammer Doom, makes a hockey stick trajectory into the pocket. However, it does not overreact like the Doom when conditions break down.
The ball looks almost exactly like the original X-Factor in its coloration.
This is my first experience with the Fire line of balls from Storm and I'm quite impressed.
