This is a very stable disc and the harder you throw it the more you are rewarded with a laser beam straight throw.

I was expecting more late fade but on harder throws it flew straight landed before getting much fade. It didn't quite fill the the hole in my bag the way I expected but it's eye-opening addition. I like it and it's my go to Mid range now. dependable in wind and can handle tons of torque

I think the glide is a touch less than 4; turn is 0;  fade It's no more than a 2 IMO

The Eclipse Vector is "overstable".  Before I had any power in my throw, it was a hard fade that I liked for medium range right to left throws.  However, now that I have some arm to me, I'm realizing that this disc is very straight with incredibly minimal fade.  So little, that sometimes I don't see it at all.  I have never seen it show signs of turn though.  I would recommend this disc to a powerful arm that's looking for a very straight midrange that isn't going to flip on them even when thrown hard.  The fade is closer to a 2 than a 3, but can be almost entirely powered out if that's the shot.  The rated speed and glide are spot on with what infinitediscs has on it.

I have a 178 eclipse vector and it is my favorite midrange and probably my favorite disc. It is basically the same as the roc3 but wears in slower. It is also flatter than the roc3 which makes it a better feel for forehand upshots. This disc is very consistent for me and holds up well in the wind. I highly recommend to anyone looking for an overstable mid or something to replace a roc with. It feels great in the hand and the eclipse plastic looks awesome as well

The Vector is a very useful midrange. When thrown flat, it flies straight with a little bit of fade. As it wears in and the bead takes a little beating, the more versatile it becomes! With some snap it will even hold an anhyzer line all the way to the ground. For beginners, it will be a little overstable for some but if you've developed a solid release then the Vector should suit you nicely. If you like the Roc3, or the Prodigy M2 and want to see a little more versatility and durabilty, get a Vector.
