I was talking to someone yesterday and he just came back from a week in France
he actually witnessed a delkim melting in the heat lol
that one definitely won’t be waterproof
Whilst it is unlikely
it “could” still happen with a running lead.
that same wind knot “could” loop over itself pig tail and lock in the lead Ala a single granny knot.
“could” pick up a piece of detritus on the bed and do the same.
unless you can take out every “could”
You will always be left with an element of risk.
i am happy to use a leadcore leader but I will use a knotless knot (Moors knot ) to join it to minimise the risk.
Use a Korda no trace bead and again take out an element of risk
i would be happy to see the no trace beads more supple/stretchy rather than hard plastic.
Don’t care what anyone says, There is no fool proof lead set up
the best you can hope for is to minimise any problems if and when it happens
underwater, anything can happen once the line has snapped off.
