trolling crankbaits with leadcore?

[zipper]

I just don't know or understand how to get crankbaits down to the 40 to 50 foot range

[Prime Time 2]

I run 5 color lead cores, reels are mono backing, 5 color, 40' leader.. a reef(will dive 25' alone) now added to the line, now let ,leader, all lead core and an additional 50'. the lure will now be 50' deep..
good luck Rick
In order to spool lead you must remove a lot of the mono from your reels,
