I hear a lot of people having trouble with tying the FG Knot. The FG can bee quite a tricky knot to learn and tie properly. Here is a knot with similar characteristics (Tag end facing straight and high strength) that is a lot easier to learn. It still is not the quickest knot in the world to tie but not as tedious as the FG Knot. Hope this will help!
