I use 80lb stren coral fluro on my 280g rod. breaks close to 100lb. think the epic boys use 100lb

Yep using spin gear, so you would recommended to use mono then as it coils better on the spool. any particular brand or just black magic 80-100lb supple trace?

Great do you use the supple or tuff mono and can you recommend a few of your favourite jigs.

Personally would avoid the supple leaders, they tend to cut themselves on the solid ring. Since fluorocarbon is out, buy yourself some Jig Star Knot Sleeve and use this to protect the leader knot at the solid ring. If making your own assist hooks, then buy the Jig Star Double Ring and Grommet then you can use your supple leader.

Sounds like you are gettting there.  Most jiggers would not have a split ring anywhere in the connection between  hook and mainline, only using split rings for attaching the jigs.  Your assit should be looped through your solid ring, and a split ring for your jig only.  Means you dont have the weak link of split ring when fighting a fish and easier to change jigs, without changing the assist.  I recommend the FG knot over the PR.  It is both easier to tie and stronger in my experience.  As for jigs-they all catch fish and cheap ones are good when the cudda are about! A few different colours and weights is what you should focus on rather than the brand.  I jig with 200gm to 400gm jigs out of Tauranga at Schooner and Mayor, depending on depth, current, drift speed and how tired I am.  Go get em!
