with some sass knowledge you are better of starting off with a couple of mixins and building from bottom up as compared to loading a fat css file you probably won't use 80pc of its rules.
Normalize css[1] Bourbon[2] for utilities Neat[3] for the grid, Typeplate[4] for a nice type base.
If you still need bootstrap style elements, you can get individual mixins and styles from one the bootstrap-sass projects[5]
