Hi Zack your off to quobba hey, I would highly recommend a wind on leader off min 80lb as the ledges there are basically oysters and braid won't last 2 sec against it. But to join the two can be a bit difficult I have found the Bimini twist is your strongest not to join them but is a pain in the ass not. I have found that it is a lot easier to use mono up there .

depends on the purpose, but usually lures, droppers, gangs perform much better when on a leader.

for lazy fishing, ie: chasing some plump whiting in the sound, i can sometimes be lazy and not put a leader on a small dropper... but anything bigger, dhus, pinks, or anythign up north, always have leader.

I always use "wind on leaders" some say theyre expensive but unless im bricked or snag bottom i generally get 12 months out of them before i replace them so not expensive at all. 

Its called a catspaw (multiple loop to loop) to join braid to the leader. Ive never had a failure to date.

 def go leader . my leader is generally 80lb and about 4mtrs long. best way to avoid chaffing of braid on rocks and coral

I am with your old man, have fished with braid for over 10 years and used leaders very seldom. I have found if you use a longer dropper on your rigs it has much the same effect as a wind on. have always used much the same knot as mono just double the line and go more wraps. Although if fishing really ledgey type bottom i can see how the leaders would be of some advantage.Up to you trial and error,and work out what best suits your type of fishing.

Go as long a dropper you cast. That's all I use there, the reality is fishing at quobba you will get snagged or sharked and a wind on leader won't help you one bit. You want to be setup up to quickly tie on another rig or lure and cast out. Most people spinning lures use a wire trace 300mm long and about 500mm of 80lb+ mono then tied however you like to your braid. When snapper bashing try the longest leader you can cast which is usually just over 1 metre

 when i landbase baits i use braid to 40-100 lbs leader of rod length and casting drop tied with either allbright/PR/FG then to multistrand wire up to 100 lbs tied with allbright then tie on hook with a knot that barrel rolls down the shank and tag shoots under rolls,

sorry dont know name of that knot  also have running sinker on leader or wire. I dont use swivles up here  

Guys also dont forget the mono leader provides alot of stretch when a fish strikes and you strike back! When I first started using braid a mate told me I didnt need to tie the braid to mono and he tied the braid straight to a swivel, next cast mr salmon comes along and snaffles my live mullet, I strike and the braid snaps instantly just because there was no stretch.
Ever since then I've always tied on a mono leader via double uni, I never cast that knot through the guides unless its like 8lb leader..

cheers for the reply guysss, what brand of leader would yous suggest, i want to use leader sounds like it all makes sence heey, but dno because theres heaps of roacks around, sharks and might gett hammered so maybe a leader is a waist of time up there, because a bimini twist with 30 knot easterlys on the rock isnt what you wanna do out and aboutt
cheers tho guys helped heaps
