Do you retie your leaders after a certain period of time?  I put about 10 feet of fluoro at the end of my braid about a week ago.  Used an alberto's knot with a dab of super glue so I believe I'm fine for now, but wasn't sure how often people retied their leaders.

i use my same leader till i get about 18-20" to my main line then ill cut it off and put a new one on,or if it gets all knicked up then i swap out asap.

I only retie when it gets too short from hook retying or if it gets roughed up. I start at about 4'-5' and replace at about 2 1/2'. I use the uni-uni knot connection.
