leader with yo-zuri

what size leader should i use when using yo-zuris. dont want to loose them i notice most people use leader

I personally use either 30lb or 60lb 7 strand depending on the water clarity.

I'm using the same I use with a treble for live bait on kings, after all the teeth are the same.
30# AFW seven strand.

so the 43lb steel leader no good

Depends on what you're fishing for and where.

I use 10-20 # fluoro for specks and flounder depending on conditions.

At the pier, I'd go with wire as mentioned above.

alrite thanks is there any particular brand

[size=12pt]I use SevenStrand or SurfStrand 27#, J & M has SurfStrand.[/size]

do you just tie it the same way you tie steel leader (haywire twist) ?

I like figure 8 or a single wrap fish n fool with 7 strand, but it is just as effective with any basic knot.

Haywire Twist is best for single strand.
Some others (IIRC, Pier#r for one) here said that a simple overhand or double overhand will hold with seven strand.

I've been doing an overhand with several 90'twists and it has held like it was welded together.
