Vanilla sass without bootstrap?

Can anyone provide some tips on how to go about removing bootstrap opinion throughout the theme, without breaking anything? And with updates to sage I don’t want to have to be changing too much etc

I tried converting the menu into susy grids and javascript with fa, but a lot of it is tied into the nav.php, which I couldn’t figure out how to simulate without the bootstrap classes and data attributes!

Any help would be much appreciated.

bower uninstall --save bootstrap then go ahead and start hacking on the styles. The bootstrap classes can be considered a coincidence, just use those classes with Susy or bourbon neat or whatever.
