menu omega responsive

I know this topic has been in flux, but I wanted to check in with those of you using Omega and find out what you are using for responsive menus?

Right now we are hand-coding our menus as blocks with a UL/LI structure parent/child structure. They are horizontal with drop downs on the desktop view, and show as vertical with sub-items on the responsive.

However, we want to switch to menus that are managed by Drupal with responsive styling built in. (Possibly with a clickable Javascript box for the menu instead of a persistent menu block at the top.)
