Re: Outfitting with down riggers
Maybe I'm misreading your question, but you shouldn't run "metal line" (wire line) behind a rigger.
Same with the lead core suggestion...unless you plan to dredge the lake bottom!
Wire line on the rigger itself to the ball - yes.
Mono or braid on your rigger rods is the norm.
On the internet, EVERYONE is entitled to their opinion!
