FA- I always run approx 30 ft. of mono off the end of the braided. Not my idea, picked it up off my guide buddies. Works great, remember to use a suitable knot.
Also- I only have a stacked release clip slippage issue if I try to pull the line off the clip. I have generally learned theres no or minimal advantage to stacked lines where I fish, however if I do, I will bring the assembly up on the downrigger and release it manually.
