I use a knot that essentially hybridizes a traditional Homer Rhodes loop knot but starts with a "Figure 8" in the main tippet line. It finishes with a half hitch as a jamb knot to finish things off. I've found this knot to be easy to tie, efficient, and provide small and well centered loops.
It's nearly identical to the Steve Huff Double Figure 8 except the jamb knot is a single half hitch. Both are great options, this is my personal favorite.
