Elevation EcoFirm Capybara is an understable midrange with a similar feel to a Buzzz SS or Mako 3. These are Rubber discs are very flexible, but they are more firm than the OG Rubber Blends. This blend does not fold over in half as easily.  

From Elevation Discs: 

The Capybara is an understable midrange with flight numbers 5 | 5 | -2 | 1, similar in feel to a Mako 3 or Buzzz SS. It has a low profile and very comfortable rim. It can get really good distance on a straight line, amazing for hyzer flips, turnovers, or controlled distance for lower arm speeds.
