For intermediate players you're going to want to beat this in a bit because out of the box, it's an over stable utility disc. With some time though, it's a very unique disc that can get you some decent distance and still fade very hard, even in heavy winds. Also gets pretty great ground play for those hard corner flare skip shots.

The EXP-X feels and flies just like a beefy Eagle-X and I think of the two rather interchangeably.  The one I have has some dome which feels a bit off on the forehand, but it feels great on a backhand.  I've got one that I'll sometimes throw when the wind is whipping. 

This is my all time favorite disc. It hyzer flips and has great pushing fade. It is stable in that it resists turnover, but it wont nose dive into the dirt every time you throw it. Both runs feel incredable and are pretty domey. Im gonna be honest, this might just be an Eagle X. The Millennium website does indicate that the bottom of the disc is the Eagle X mold. I am not sure about the top of the disc. Maybe it's just the run, but ill take the Exp-X over the Eagle any day.
