1. Why use lead core. Why not use downriggers?
Depth control. Lead core is a great way to accurately present a variety of baits (spoons, harnesses and shallow diving cranks) where they normally may not have been designed to go. Lead Core also doesn’t require as much specialized equipment as Down Riggers, downriggers, cannon balls, and mounting hardware are an additional expenses, and may not out produce lead core and in some situations can actually spook walleye. Downriggers have there benefits too, they work for very deep walleyes (over 40 feet) or when fishing with a group. It's all about maximizing your time on the water and catching more fish.

2. What is the benefit of lead core?
Lead core is one of the simplest methods of presenting baits in deep open water applications, it can also be used to provide precise depth control when contour trolling. Lead core line is essentially a dacron wrapped lead sinker that has been colour coded every 30 feet, simply by counting colours as the line enters the water you know where your lures are running, no additional weight is required to get your baits into the targeted depth range, the baits sink or rise with the line.
3. What is the worst thing about leadcore?
I don’t' know if theses are the worst things, but 'core certainly has its drawbacks. First it is highly speed dependent, it is lead after all, the faster you go the higher it rises in the water column the inverse is also true when you slow down. Second, it is very Bulky, so it requires a large capacity reel to hold enough colours for your trolling applications. Third, as the lead sinks it creates a "belly" in the line before the leader, some lures (spoons, harness's and shallow cranks) may run above the belly in the line, while deep diving cranks may run below the belly, changing the precision of the presentation depending on the lure.
4. What special things are needed for leadcore? Line counter? Limp or heavy rod. Long rod/short rod? Large reel?
Large capacity trolling reels are a must with lead core, even if you are segmenting the lead core for specific depths in open-water situations (This is something we really didn't discuss, it entails using a specific number of colours for a targeted depth, longer leaders and more backing. It really limits your flexibility as you are stuck to a targeted depth, but excels in open water situations as it lets the planner boards run better) there is still a pile of line needed demanding a bigger reel. I also prefer a line counter as it allows you to make small precise adjustments when contour trolling, but it's not require by any means and not necessary in open water. My personal favourite is the Diawa SG47LC but the most famous lead core real by far is the Penn 320. Rod length and action are a matter of personal preference, one thing to keep in mind is the limited stretch of lead core and its rope like consistency. I prefer a rod that has a slower action and is longer to provide some forgiveness that the line won't. 8 foot 6 inch Diawa heartland rods have a nice long handle to fit in the rod holder, the right amount of forgiveness but plenty of backbone to bring in fish over ten pounds.

5. What type of equipment. Tell me your favourite stuff!
Lead core trolling will require some specific equipment.
First, Good quality Rod holders as lead core is heavy and holding a rod gets very tiring after reeling in a fish caught on 6 and a half colours (over 200ft of line). Scotty Power Lock rod holders do a great job of controlling the rods and provide the flexibility of adjustment to make refinements to your rod spread.
Quality terminal tackle - Ball bearing swivels that can be reeled through the rod guides are the simplest way of connecting the lead core to your leader material and reduce line twist if a smaller fish is hooked. Berkely Cross-loc snaps are great for attaching the baits to the leader and allow for frequent changes in lures if nothing seems to be producing.
A smooth running reliable kicker for precise trolling speed, lead core is highly speed dependent and quick idling or stalling motor can make for long days on the water with no fish and lost lures.
Lead core fishing is often used to present baits to deep suspended walleyes in open water applications such as the great lakes. Anytime you fish "big" water either on the great lakes or the Kawarthas you need a good quality boat with a deep V to get you in and out of situations that often develop, run a Princecraft 198 tournament and have been very happy.
A good Quality Net with an extension handle - Hopefully using lead core means bigger and more fish in the boat and because you are using long leaders, sometimes longer than the rod, a good quality net is essential to ensure that your next trophy is not lost.
Precision Trolling, by Marc Romanack. This is the troller’s bible and provides drive curves for all of the most common baits on the market. It also provides estimated depth for segmented lead core set-ups at varying speeds to take the guess work out of most trolling situations. This is a must if you plan on trolling consistently for walleyes.
6. Size (pound test) of lead core, leader and backing
and why?
The most common size of lead core used when trolling for walleye is 18 lb. The rating actually refers to the strength of the dacron sheath that surrounds the lead. The lead diameter stay the same after 18 lb, the dacron just gets thicker resulting in a bulkier set-up. Therefore 18 allows you to spool more on a smaller sized reel than would be achieved with heavier tests.
Here is the process I use for filling reels. Spooling the right amount of backing, lead core and leader is achieved easier with 2 rods with the same size reels, and is done in the reverse order to what it will be fished. First tie off your leader to the first reel, and wind on the desired leader length, I use approximately 10 feet of 15lb Mono for open water applications and prefer Berkley Sensation for its smaller diameter and abrasion resistance when hooking larger walleye with big teeth. Attach the leader to the lead core using a small ball-bearing swivel that will travel through the line guides and levelwind. For a smaller more compact knot in the lead core remove 2 inches of lead before tying.

Spool as many as ten colours onto the reel, or the maximum amount that you will be using. To splice the lead core and the backing, first remove 2 inches of lead from the dacron and tie an overhand knot in the end, next insert the backing into the center of the Dacron and tighten the knot. Now spool the backing over the lead until the reel is full. I prefer 15 lb. Berkley Big Game for backing, the higher pound test allows shock resistance in cases of an incidental salmon catch.

Removing the Lead
Now crank the entire line system starting with the tag end of the backing onto your intended rod and you have the exact amount of backing, core and leader to fill your reel, and if you were using a line counter and were paying attention when you connected the lead core to the backing you now know the exact amount of backing the other reel will require.
The second set-up is used when contour trolling and is a completely no stretch set-up that allows for the detection of debris when trolling close to the bottom is shallower situation. This system uses no backing and is a full ten colours of lead core attached directly to the reel followed by a 50 foot leader of Fireline.
There you have it....If need any other info just let me know and remember to keep letting them go!
