@xav so sorry, I thought I’d replied to this. I don’t necessarily prefer Bourbon, in fact I’ve used Bootstrap for probably the last 3 projects I built. I really like both of them.
Which I choose really depends on what I have to build and how quickly I have to build it. I like Bourbon because it’s so light weight, but I can move much more quickly with Bootstrap due to all the cool stuff it comes with. That’s just me.
Sorry again for the late response, better late than never though. 
Hi @smutek that’s great news! i’ve been using Bootstrap 3 a lot and Bootstrap 4 alpha looks great to, but like you told to @xav , Bourbon with neat and refills are really lightweight, i really see the difference when i run the Gulp build command 
And when i need some extra components i often grab my inspiration and scripts ressources on the awesome Codyhouse bourbon Library !
I won’t forget to share the link of the wordpress bourbon sage 8 i’m actually working on when it’s on production 
Do you know some other Bourbon refills extra components library?
Thanks again for your quick reply. Can’t wait to install the Bourbony sage 9 package!
Nice, I hadn’t heard of that, bookmarked, thanks!
Hi @smutek @ben
It would be great if you could add the following fork to your docs official list:
I’ve been using this fork for my last projects, and it is a great alternative to bootstrap !
Here is a “work in progress” beta version of my latest project built on top of the BourbonySage fork:

I wish you an happy cody new year!
Hey, thanks for the shout out, I’m glad you’re still finding the fork helpful!
Hi all.
I am using Sage 9.0.0-beta.2. Just in case you want to try this puppy with Sage 9…
After fully installing the theme, I ran npm install bourbon-neat and was able to import the core styles into my main.scss file using @import "~bourbon-neat/core/neat"
I’ve been using Bootstrap v4 but find that even after I customise the build, the CSS just gets a bit out of hand in terms of file size, especially after the webpack autoprefixer kicks in, so the lightweight nature of Neat is quite appealing. We’ll see
I’ll definitely check out your fork, @smutek - sounds good, although I’m now fully committed to the Sage 9 branch - loving the Laravel Blade templates and fast builds.
