If you need a mid that's torque resistant, this is great. If you need an overstable mid, or a wind fighter, not so great. The hand feel is much more sleek than an MD3 and just great in general. So aside from the numbers being very misleading it's a great mid. 

This is absolutely fantastic. There are a lot of similarities between its brother the md3 with md4 being more likely to be on the stable end and some md3s being quite flippy. I don't think an md4 is going to be stable for a long time so I would expect to cycle them and drop md3s entirely. If you find this disc to be too straight an md5 is beef. 

The feel of tthe md4 is reminiscent of the verdict by dynamic discs. With a bead. I really enjoy the metal flake c-line plastic. It is very durable and looks great.

The flight of this disc is very predictable. It goes on the line you throw it on and will fade at the end. It does not have stellar glide but it is a fair trade for how predictable it makes this disc.

I use it for an upshot mid where a disc like a buzz or rift would glide too far but a putter would be too short.

The md4 can be used by all skill levels.

Everyone needs an overstable mid in their bag. This is great disc to use in that slot. When you get in trouble or in that tweener distance and you just need to chuck a hyzer and stick it under the basket, this will do that for you.

The MD4 I received is 180 grams and it is pretty beefy. The rim feels nice and gives a nice release on both forehand and backhand releases. On a full throw, I was only able to get about 250 with backhand. The MD4 stayed straight and then had a strong fade at the end. I also throw a Justice and the MD4 is not quite that overstable. I could see it being used for those 150-200 foot upshots or when you get in trouble and just need to get around something.
