Tying the braid to a swivel may work , as long as the knot is not slipping under heavy drag but then there is a problem of braided fraying when being cast , presumably you use gloves when fishing ,
other problem you may encounter is a small toothy fish hitting your swivel while working the lure .
I wud rather avoid swivel but just crimp a mono leader on both ends and tie directly to the braid and use splitring to facilitate the changing of lure at the other end of the crimp .
However , I still think mastering a particular knot is usefull and in my case , I use MidKnot exclusively when GT/Tuna popping .
