Apart from joining the mainline to the nylon backing on the reel I would never trust any braid to nylon knot , i always join braid to nylon with a swivel, I tie a snap swivel to the end of my braid mainline with a uni knot

Then clip anything I want as end tackle into the snap swivel , I never use braid in the rigs or end tackle in any way , rotten bottom mono for the lead and a swivel tied to mono clipped into the snap swivel for the trace, or if I'm using a daylight rig for example I'd clip that straight into the snap swivel and attach the lead below it, so mono never ever gets tied to braid.
