Lead core and "colors"
Put a 30-50' leader on the lead core with a Willis knot. use mono or fluoro - your choice. Replace when down to less than 10'.
Farted, thats a lot of work to tie mono between each color, but I suppos if you want to clip it to boards, thats what you gotta do. I fish lead, but not necessarly the great lakes.
When using lead core, do you tie the spoon/lure directly to the lead core? Or is it best to use a leader?
I've said this before, the biggest issue pinching off a 10 color is the added weight/droop creating in the line running from the board, back to your rod tip. That weight sits in free "air" and bounces too much.
The least ghetto of the ghetto approaches I've ever heard....putting 10 total colors on a reel, with 150' of mono spliced into the middle of the core (for example: 5 colors, 150' mono, another 5 colors). Like I said, pretty junky.
I recall trying to pull a full core with a yellow bird a number of years ago and it didn't work very well. I'd second the Offshore recommendation or Church Tackle TX-22.
You can pick up penn 309s on eBay pretty cheap for your core rods. They have a great gear ratio for lead core and you don't need a line counter since you know each color is 10 yards.
