Flydunker, lets not revisit the "Expert Thing"!
Your in for some fun and good eats, if you like fish that is.
I think I have learned a few useful lessons rigging 2 boats (so far) for Great Lakes fishing.
1) Buy good rod holders, I had lots of problems with the "Tite Lock" swivel base rod holders, the disc that locks into the base strips out easily. I use "Berts Custom Tackle" rod holders now, and wouldn't trade them for anything. But they are very pricey! The "big Jon" holders also look pretty well made.
2) You don't have to pay big bucks for 'rigger rods, I use "Ugly Stick" BWD1103, 8'3" rods for riggers and boards, they run about $40 each (less on sale), and they stand up to a lot of abuse. I also have 6 "Fishmaster" 8'6" rigger rods that are about 20 years old, I love these rods, but I don't think they're made anymore. "Diawa heartland" dipsy rods are affordable and work pretty well so far(one season). Still working on the lead core set up.
P.S. I would not buy graphite rods for riggers or boards, fiberglass will hold up longer and won't "snap" on a big fish.
3) Quality reels are a good investment, Diawa level winds are all I own 27H, 47H for riggers, SG27LC, SG47LC for boards and dipsies. Line counters make getting your baits back to the exact depth quick and easy.
4) In-line boards catch fish! I use "Off-Shore" boards. Take out the lead weight and cut an equal amount off each end to lighten the board by about a 1/3. Take the Release off the back and replace it with a snap swivel, use a barrel swivel and a bead 6-8ft above your lure to stop the board after it releases and slides down the line.
Okay so theres a lot more for me to learn, but its a start!
Some other preferences: Trilene Big Game, 20lb for riggers, 15lb for boards. 30lb fireline for dipsies.
I own 4 Walker electrics with ball retrievers(love em'), But most of the people I know that own Big Jon's swear by them, Including the manuals.
