The MD5 is overstable. No wind or shaky release will change that. If you are looking for a dependable, no questions asked, goes where you tell it to go midrange with an awesome feel, look no further.
NOTE: The Innova made and Discmania made MD5's are VASTLY different in hand feel. The Innova made ones felt similar to a Gator, with a large, chunky rim and a bead. The Discmania made ones feel much more like a modern midrange. The shape of the rim is comparable to a 5 speed Zone.
 
For reference, the specifications for the Innova-made MD5 are D: 21.1; H: 1.9; W: 1.4; D: 1.3.
 
Discmania's Horizon C-Line is a beautiful, premium plastic that has a ring of color around the outter rim of the disc. It's similar to Lucid Orbit plastic from Dynamic Discs.
