Id go 40lb for sure

 Hate losing fish so after some trial and error have settled on 60lb now.

I use to fish 20-40lb. After losing a few big fish on rocks i now use 80-100 haha

That high? Even on 20lb main?
- how long you go for?

Sorry i actually run 60lb leader and run a 80-100lb rig I am running pe3

On my PE3 I run 80lb - but I just make sure I use good quality (and thin) 80lb.

On PE2 I run 40lb.

This is with metal jigs though - I know many people like using lighter. Just personal preference I guess. The amount of times i've been jigging and brought back frayed leader due to hooking a shark, catching some rock, a glance with a pike or a makkie or something makes me think that on lighter leader I would have just been pinged.

Different story again for casting.

I use pe3 (50lb) and 60lb fluoro, bout a rods length. 50 turn bimini to a gt knot and an ocean snap, makes changin lures/jigs easy. So far so good

I lost a nice duh, was thinking of going up to a 50lb or something cause it hurts when you feel the big head shakes and then zzzzz and a big pop
Got it on video and I had some choice words to say.

Fluorocarbon all the way 40 pound does the trick

30 lb thin flouro on PE2 is my choice.

Definately higher hookup rate than heavier leader, also Definately higher loss rate due to being bricked. Anything over 15 KG dhu is 50:50 on such light leader based on my hit miss ratio. I'd rather hook em and possibly loose them if I'm not good enough.

I reckon 20lb is definitely too light. Dhu has abrasive teeth to wear out leader if not, they will usually dive underneath a cave after hook up.

40lb fluoro leader is a minimum in my opinion.

Hooked a good size dhu on Whitey's boat and it went underneath a cave. Everyone including whitey said I snagged. Eventually a dhu popped up. My 2m 60lb FC leader all frayed up. That's on metal jig.

Yep when using artificial lures offshore for demersals using anything from 40-60lb fluro carbon leader. Will agree that lighter leaders get more hits but you do need to toss up whether its worth the risk. About 2m worth is plenty.

Was up at Gero last week for a bash and some dives, old man cleaned up every day on Cray fish. But I was hoping for a big trout, took what you guys said and went for a 60lb leader, bloody lucky I did!!

While the boys where blowing bubbles I was having a jig with the plastics, casting around and jigging back to the boat and what not.

Caught a nice Coral trout but only went 44 so back he went, awesome strike, felt like a bigger fish for a bit.

As I thought, jezz; imagine the strike from a bigger... BOOM off the reel screamed and I quickly started clamping the drag down, got to full drag and it started to slow... but I could definitely feel it rubbing D:

Managed to drag him out, and it turn out to be a awesome 3kg Trout. Leader was scuffed so it was replaced with a new one immediately.

When the boys got back to the boat the Esky was filled with crays and a healthy trout. :D

i use only 80pnd - ive noticed the big dhuies swollow the plastics deep in there gullets - this leaves the mouth to rub past the jig onto the leader line causing severe fray, anything smaller it would have snapped, rather be safe.

 30lb braid 100lb leader4-5m long. rigs 100-120lb .that one big dhuies isn't worth losing on the light gear. Watched others on my boat bust of time after time they, soon get sick of dropping big fish.

For soft plastics i still use the 100lb leader stright to the lead head,I seem to catch allright on thre heavyer line.

 100lb braid then 130lb mono on the rest. Anything less and the big dhu will ledge ya if he can.

id use 40 or 50lb fluoro for 20lb main line , I use 30 or 40lb braid when jigging for demersals for that bit of extra stopping power though and 80lb braid and 130lb leader when bait fishing , big dhus will rub you across the reef on 20lb too often and its heartbreaking.

 40lb is plenty... But when using bait I use a 120lb
