For fishing threadfin in HK (jigging) offshore with 20-60g jig, what is the best pe for line and the best leader weight, hook size and weight to use

Question

FishGPT · Accepted Answer

Aye, offshore HK for threadfin on 20–60 g jigs — let’s dial in a rig that catches more than just your breath on the wind. Here’s a solid, practical setup you can rely on, with a few options depending on depth, current, and vessel comfort.

**Main line / PE (your braid):**
- *Baseline rig:* PE2–PE3 (roughly 20–40 lb equivalent). This gives you good bite sensitivity, solid depth control, and ample strength to pull tabs out of structure without too much stretch. 
- *Deeper/strong current or larger fish potential:* Step up to PE3–PE4 (about 40–60 lb). You’ll lose a little sensitivity, but your fish-fighting confidence goes up when the current rips and the bites come from robust threadfin. 
- If you’re chasing the really deep or snag-prone spots, have a PE4 spare on a short reel, but start with PE2–PE3 as your go-to. 
- *Cadence note:* In cooler early-winter HK water, fish often bite when you keep the jig slightly off structure and allow for controlled lifts rather than violent snaps.

**Leader (fluorocarbon preferred for invisibility):**
- Standard: 60–80 lb fluoro leader (roughly 0.6–0.8 mm). This balances abrasion resistance and bite protection against sharper reef or barnacles, while still letting you swing big threadfin clear of cover. 
- Length: about 40–60 cm for typical jigging, longer (60–80 cm) if current is punishing or you’re fishing over sharper structure. 
- If you’re beaching or fishing in ultra-clear water with wary fish, a slightly heavier leader (80–100 lb) can help steels your strike when the bite is soft but solid.

**Hook/weight on the jig (how to set the lure):**
- Your 20–60 g jig typically arrives with built-in assist hooks. Use the jig’s own setup first. If you upgrade or swap hooks, go with a stout short-shank J-hook around **2/0–3/0** for standard 20–60 g applications. If you anticipate tough cover or larger threadfin, you can push to **4/0** with careful control to avoid overloading the jig’s action.
- For an alternate single-hook rig (some anglers like a top circle or octopus hook), use **1/0–2/0** for clear water and lighter current, and **3/0–4/0** if you’re in deeper water with bigger fish potential.
- *Jig weight guidance:* Start with 40 g in calmer, shallower pockets; move to 60 g when current increases or water depth pushes jig deeper. If you’re seeing bites but not hook-ups, try the heavier jig for a more pronounced bottom contact and snappier hook set.

**Practical tips & technique (early winter considerations):**
- Keep your cadence steady: 1–2 seconds up, pause a beat, then lower. Don’t burn the jig in cold water; threadfin respond to a composed but decisive lift. 
- Work the jig through a vertical column rather than long horizontal sweeps; target the mid-water to bottom where threadfin often patrol. 
- Depth matters: in HK offshore water, deeper channels and currents may push you to 50–60 g; in calmer, shallower zones, 20–40 g can be plenty. 
- Tangles are a risk near reefs; trim your leader to 40–60 cm and keep line in good tension during drops.

**Weather effect (season: early winter):** cooler temps slow metabolism but make threadfin snap to a prepared jig when the bite is on. Expect bites to cluster around slightly deeper horizons and during stable tides. Be ready to adjust your jig weight and cadence as water clarity and current shift with fronts.

Recommended toolkit (quick reference):
- Main line / PE: PE2–PE4 depending on depth/current
- Leader: 60–80 lb fluorocarbon, 40–60 cm (up to 80 cm in heavy current)
- Hook: built-in assist on 20–60 g jigs; spare hooks 2/0–3/0 (or 3/0–4/0 if fish run large)
- Lures: have a mix of 30–60 g jigs and a few heavier ones in case of drift
