How to Choose a Rod Optimized for Bigfin Reef Squid Eging

01Why a Fast Action Rod Is Ideal for Eging

Fast action bends only within the top one‑third of the blank, allowing the rod to snap stiff quickly. At that moment the flex is concentrated at the tip, creating a “shuts off” effect that instantly detects even the faintest bite.

Bigfin reef squid have short, sudden bites, so fast sensitivity and immediate response are essential. When a fast‑action rod is paired with an external hook (single‑hook) lure such as a worm or jig, the probability of the hook embedding in the fish increases by 15–20% (Shimano).

Furthermore, in the 12–15 °C water temperature range, squid activity reaches its peak, and Fast action quickly transmits subtle water‑flow changes so bites are not missed (National Institute of Fisheries Science, 2023).

In practice, using a line with a diameter of 0.30–0.35 mm (15–20 lb / 6.8–9.1 kg) and attaching a 20–30 g speed jig yields a casting distance of 30–45 m, and the line tip moves within 0.8–1.2 seconds on the retrieve, optimizing bite sensitivity.

02Use cases for moderate‑slow action rods

The Moderate and Slow actions cause the blank to bend from the midpoint to about three‑quarters of its length, absorbing shock and gently stimulating the fish’s mouth. This greatly reduces the risk of the treble hook (three‑prong hook) on the lure breaking when it shakes the fish’s head.

Straight‑line retrieving lures such as crankbait, minnow, and topwater often get pulled out of the fish’s mouth before the fish can fully swallow the bait.

A moderate‑slow action rod reduces the fish’s resistance, allowing the lure to stay intact and remain naturally in the fish’s mouth (Tackle Warehouse).

In depths of 50–70 m with water temperatures of 10–13 °C, fish reaction times slow to 0.5–0.7 seconds, so a shock‑absorbing Moderate action stabilizes line tension within 2–3 seconds after casting, minimizing bite loss (Korea Maritime Institute, 2022).

Especially right after a tide change (1–2 hours after the tide rises), the water flow strengthens and adds extra load to the line. The Slow‑action rod absorbs an additional 0.2–0.3 kg of load, reducing the risk of line breakage to under 30 %.

03Power rating and line‑lure matching

Power indicates how much the rod bends under the same load and is divided into seven grades from UL (ultralight) to XH (extra‑heavy). The higher the power, the more you can use thicker line (e.g., 30–40 lb) and heavier lures (e.g., 30–50 g).

Bigfin reef squid eging is typically performed at depths of 30–80 m, using lures with a line diameter of 0.25–0.35 mm and a weight of 20–30 g.

Therefore, ML (mid power) or MH (mid‑high power) grade rods provide stable casting and retrieval performance (Mud Hole Custom Tackle).

For example, when using a 35 lb (15.9 kg) line with a 40 g Squall‑head lure, if the power exceeds MH, the casting distance reaches 40–55 m and line tension during retrieval stays below 1.5–2.0 kg, reducing the risk of line breakage to under 5% (Korea Maritime Institute 2021 data).

Conversely, if the power is at UL·L level, the casting distance with the same setup is limited to 20–30 m, and during retrieval the line tension spikes above 3 kg, causing the line‑break probability to rise to over 25 %.
