G'day folks
I find that leader size is determines by the location of your targets.
If I'm fishing in the mangroves with only 5mtr casts max and turbid coloured waters, I don't use a leader but run the fireline direct to the snap swivel.
If I'm fishing clear waters in fairly snaggy territory i will use an 8lb leader about a metre long.
If I'm fishing the sand flats in clear waters i will use down to a 2lb leader as long as 10 feet long. Usually i run a 4lb leader tho in those circumstances.
However, I would love the money back i paid for the lures that have been taken from me by mangorve jacks and cods while fishing the lighter leaders. I could nearly retire on that amount!!! hehehe
