I most often use a 1/0 or 2/0 Owner J-hook on the 5 or 6-inchers, so I can switch immediately to a Texas-rig if necessary. Lately, I've been using a Gammie #2 split-shot hook, which is much more subtle, and apparently just as effective. It wouldn't work so well on the T-rig, though. It's a pretty small, thin-wire hook.

I rarely miss a hookset with that big 2/0 J-hook, though, so I still consider that my go-to setup. I jerk on it the instant I see that line pop or move to one side or the other.
