Regarding the FG,
Tip I can recommend,
Tie a simple double overhand loop in the end of the braid before tying your FG. Also, I recommend a rizutto finish. Once you have tightened by hand, put that loop around something solid, like a steel spike or anything solid you can hold, then pull it untill it welds itself. Now trim the tag. You will notice your knot has bent and buckled, perfect, now straighten it by pulling the leader/flouro both ends and then trim the leader, this straightens the knot out.
Its almost impossible to get a proper knot tensioned by hand, you might think it is, but its not.
