This disc was really weird. IDK if it was the plastic or if mine was weird, but mine is super understable. I can start on a spike hyzer and it flips up to flat, with about 50% power I can turn it over, and on forehands it flips up like nothing else. That being said, its a super fun disc to throw.

I absolutely love this disc and it will never leave my bag. If you are a fan of the Roc3 but don't like the bead you should give this disc a try. 

Another thing I like about this disc is that it has the tendency to glide a long way which allows you to get a really nice hook to the left if that's what you want. A gator will go left but I can get this to go further left bc of the high glide. 

i got this disc in p line plastic. out of the box this disc surprised me with the amount of glide that it has. because of the p line plastic it didnt hold the hard fade for very long, but i use it now for flip to flat into headwinds. it will turn over too much if thrown flat into a headwind. can still handle hyzer if i put enough on it. i recently ordered one in c line because i want the more reliable fade and will use this disc for straighter drives and up shots. great feel in the hand forehand or backhand

Amazing disc, I don't use it often but when I am playing in the cold and rain this is my go to disc. The low weight on it provides some good fixability for me and the fade helps me cut those close corners. 

I recently picked up a pair of 180 G P Line MD4s to use for a straight forehand midrange. Its not a shot that gets used very often but when I need it, I would usually grab my MD5. The MD5 would hook up too quickly and it would typically get to much skip and a firebird or any other driver would just be too much disc. I reserve the MD5 for upshots that need a lot of fade or if there's a lot of wind. I wanted to try to get the same straight flight that I get with a Roc3 thrown on a backhand, so on a whim I grabbed some MD4s since the flight is said to be similar to a Roc3 but with out the large bead. Beaded discs don't usually bother me for forehands but the Roc3 is just uncomfortable to flick. In the hand the MD4 feels very natural for the forehand grip that I use. The 2 that I have are nice and flat and when I get a nice clean release with it the MD4 will fly very very straight and then have a nice soft finish to the right. This disc also does not skip much at all. When I need for forehand shot to go as straight as possible, finish softly to the right and not skip very much, I'm grabbing my MD4. As far as backhands, I can not attest to how it performs as I haven't thrown the disc back hand yet.
