i personally use Fisherman offshore 55lb. really supple, nice to tie and thin. bit pricey, but it is definitely worth it. Good luck finding it in your local though. have not personally found it. 

I've only used the black magic leaders, but have had no issues. 20lb fluoro for soft plastics and 40lb tough trace for trolling. If you're looking at abrasion resistance, the tough trace may be the way to go. Supple, easy to tie and strong. 100m spool costs around 30$ so that's not bad either.

It has the 2 kinds. I find them both pretty good and very durable. Have caught some nice fish on them with no probs. And its pretty available most places. 

another vote for Black Magic in supple or tough modes, same for Jinkai green (soft) and red (tougher). Both decently priced and never had a problem with either of them

I use the JM Terminator shock leader for everything except ultra light tackle stuff.

 I use the Black Magic supple for the leader and the tough for the terminal trace but also occasionally use the Black 

Magic Fluorocarbon as well. The tough trace is great but the Fluorocarbon is a bit better. I've got most spools of all up to 130 lb to suit all kinds of fishing. The fluoro only goes to 80lb though.

all the way. Supple for game leaders and tough for traces. I've had a bad batch of Jinkai so never again. Not sure what was wrong with it but had very poor abrasion resistance.

Personally don't do any light tackle stuff like Breaming so don't see any reason to pay the rediculous price for Flourocarbon.

 Berkley Vanish anyone??? 

i like the jinkii, have been using it for ages now with no issues at all, good price and easy to get.

It's the jinkai that I have been using.  It's been ok but the abrasion resistance isn't up to much , which is why I wanted to try something else.

I do use the black magic fluro in 20 , 40 and 60 for plastics and light jigging so may get some of their mono to try too.

mate, i have no issues as i normally lose the rig before it gets a chance to wear out..lol

i only use the 120lb for my b/b rigs and then 40lb for leaders, did notice them getting a bit roughed up at jurien last week, with one rig lasting me 1 1/2 days, i was happy(sort of) when i lost the rig and had to get a new one out.

but tell you what...im getting sick of making all the rigs for my boat and the boys think its a never ending bottomless bag of rigs, compleate in sealed bags fully rigged ready to go, just add the sinker!!

might start hiding my own private stash and make them make there own out on the boat, then they might see what i do.....

rant over!!

I also had the rigs repeatedly snapping at the twisted dropper knot when under only half decent load.  pretty poor.  I probably put 4 complete twists in before passing the loop through, when tying them.  maybe need to do a few more twists

yeh mate, i do 6-7, had no probs with snapping, even after some shark hook ups, snap the main line first normally, what lb??

cause i found when i was using a bit lighter i had that prob, from memory it was 100lb, it was a while ago now

edit.. only prob with the 120lb is getting the double in the eye of the hook, i found the 8-0 big red snapper hooks the go mate, cheap and still strong enough, i did hav a couple of blowies bite them in half though!!

I use Schneider for all my leaders above 20lb both boat and landbased. Trace lines, rigs, wind on leaders/shock leaders. 30, 40, 55, 70, 110lb. Love the stuff. Easy to tie knots even in the heavier stuff, and way better abrasion resistance than when i tried Jinkai(both types) and Black Magic, my personnal observation. But it also does come down to what you are fishing for, how you are fishing for it, and where you are fishing for it.

Below 20 lb i have been using Sufix or YGK flurocarbon.
