try a palomar knot for your jigs. if you cinch it right, then it wont slide around on your jig eye.

last year when i was using braid, the rivers inlet knot was the main knot i used for tying braid to a swivel. depending on what brand braid you use it will still slip though. i use power pro whenever i do use it and had no problems.

nothing else do a search for knots and find some that'll suit your needs.
