Personally I would not use a steel leader unless I was specifically targeting pike. If you are concerned about catching the incidental pike while targeting other fish and losing your tackle, a flourocarbon leader in combo with a swivel will greatly increase you chances of landing said pike while retaining your tackle.
I've landed many incidental pike while fishing for walleye without a leader. If I am specifically targeting pike I will use a titanium leader, which I like better than steel because they don't kink and don't rust. They cost a little more, but I've had the same two in my tackle box for years, so no biggie. Usually I'm fishing for walleyes or small mouth, and I don't use a leader. Occasionally I will lose a piece of terminal tackle to a pike bite off, but that's a price I don't mind paying, and it's a kind of an exciting experience in itself.
i use some type of a leader. i dont mind that the line breaks or i lose a lure. i would rather it come back unusable and i pack it out than to have it sitting on the bottom of one of those beautiful lakes.
I fish pike a lot in & out of the BWCA & almost always use a metal leader of some sort & have only had a handful lost over the years.
On the other hand, I have a friend who uses 20-25 lb. test for a leader on pike, & I've rarely seen that heavy line fail. I've taken to using it for leader material on tip-ups in the winter & haven't had a bite off yet.
So both work, but I started using leaders & it works, so I've stuck with it. Although now that you mention it I might just through some of that heavy fluoro in the tackle box this weekend...
I am by no means an expert and I use flourocarbon leaders in 10# on my level wind reels attached to my braided line but didn't realize that the flourocarbon was that much tougher than regular mono, I have used because it is less visible. If you are using it for pike what pound test and how long a leader?
When I troll, I use a light, small steel leader. Keeps the pike from eating your eight dollar raps. In my opinion, when a bait is moving along at a pretty good clip, a walleye doesn't have time to reject it because of the leader. Jigging, rigging, and bobbering are another story: never use a leader.
i make my own leaders and still use the old school 7 strand braided steel covered in plastic. i connect right to the lures and use one larger size barrel swivel up top. but this is also just for targeting pike. other wise i don't bother with leaders, but i use a lot more jigs for eyes and bass which are a little easier to loose than raps
