SASS in a Theme, best solution?

Hi, i want to use SASS instead of CSS in my first theme…is it a good idea? I’ve just installed on my linux PC SASS, it is awesome!

I found this plugin WP-SCSS, but it isn’t popular.

I use ad starter theme Unserscores, but I don’t tick the advanced option “_sassify!” and it’s a big problem for me now!

Best solution? I’m confused.

Thanks
