Keeping spare traces on a rack will reduce your fishing downtime if you get tangled with others, get snagged or are busted off by a big fish.
You can also bait the traces while they are on the rack.
Running repairs only mean seconds of lost fishing time rather than the many minutes it takes to completely re-rig your line from scratch.
The main question we get asked at Paul's Fishing Kites is, "how to tie a knot for fishing traces and get them all exactly the right length?"
The first thing you need to do is tie or snell all your hooks to traces that are around 300mm (12inches) too long.
For snapper fishing one metre 20 to 30 kg (40-50lb) traces are best.
