I used to use a leader with braid but rarely do any longer, especially for Crappie. I sometimes use the loop knot and sometimes use fas-snaps just because I like to switch jig head colors sometimes. With the fas-snap I just tie it into the loop and can snap on or off the heads. I still use a flouro leader sometimes when fishing for other more spooky species. When I use a single jig I sometimes just clip off an inch or so of the braid and retie the head. Keeps the end of the line fresh.
