Hi guys, I am after a baitrunner and I need advice on what to get. Most of my fishing is in 30m deep and I use 30lb braid with 2-3kg drag, straylining whole squid, whole pilchard, or a slab of fresh kahawai. Will I need a 4000 or 6000 spool for a thunnus? Thunnus 4000 Capacity (braid lb/yd) - 15/270 20/190 40/145 Thunnus 6000 Capacity (braid lb/yd) - 30/245 50/210 65/130 Thanks for the advice!!! 🐟 |

Softbaiting/ straylining baits etc I use a 6000 OD ( basically the same as a thunnus, just lower 'grade' model) for deeper water .. getting over around 20m... on 15 kg rod Below about 20 the thunnus 4000 or 4000 od on 6 to 10kg 7 to 7' 6" rod Reason is more the light weight rod, has a lighter lure weight rating. and out in the deeper water there are often more current, may tend to drift a little fast so need the few oz s

I think it's always an advantage to have a rod/reel combo that feels balanced in your hands. So my sense is that unless you're using a pretty lightweight graphite stick similar to a soft baiting rod, a 4000 would be too light in weight (not from a fish-handling sense).
I do use a combo like that in the shallows when straylining for mostly small pannies. I wouldn't use it if expecting to encounter bigger fish near foul territory, though. I wouldn't rely too much on the stated capacity, as no two braids are alike in terms of diameter. You won't really know until you wind it on. In some ways, it's easier to get a shop to load your braid from a bulk spool, as if you need 340m, you won't want to be 40m short. I've had some fun and games trying to put 150m of a nice Japanese 8-strand braid on my soft bait reels, over mono backing!

| I would be inclined to go for the larger reel capacity just in case a kingie pics up the bait, but I like balanced setups, so if you have a lightweight rod, the 4000 may be the way to go. The line rating of a rod doesn’t mean much to me as there is so much variation even within the same brand. |

Thanks for the advice guys. I bought a Thunnus 4000 in the end with 20lb line as I mostly catch Snappers from where I fish and hardly any Kingies.
