it's been said many times by various anglers... and then there are the cries of the faithfull to the stuff, shouting down the arguments against it... "it's safe if you know what you are doing" is a famous argument for it..... but who is to say who knows what they are doing, it only takes the line to hit a mussel shell or gravel bar and the potential is there for a snagged fish... I stopped using it years ago, in part because of all the horror stories around it, but mainly because most waters round my neck o' the woods have banned it.
Here's my take... it doesn't lie flat on the deck, it bridges dips and depressions on the lake bottom, looks blatant, can snag or tether fish if you get cut off...
I can see no upside to it.... other than abrasion resistance and there is no guarantee that any abrading of your end game is going to be on the leadcore section... (I did hear tales of folks using 6' plus of the stuff a few years ago.... )
That said.... if it's that dangerous why have Korda and other companies persisted with it's sales, and I heard t'other day that Korda have brought out short pre spliced lengths in packs of 6 for use with solid bags... TBH I can see a use for a short leader for that application, but leadcore....???? (why not just use tubing?)
If you take the arguments against leadcore a stage further are not ANY leaders that safe...? given the way in which it can tangle or tether... Surely the safest rig has to be a freeline with a hook and bait and nothing else, and even that can tangle and tether (admittedly in very extraordinary circumstances) so where do you go from there... ?
I'd love a system where I can make up solid bags on a ready made leader and just slip a loop over it and cast it out... but if it's going to be that dangerous I'll pass on it
