I'm not looking to challenge anyone on the barb vs. no barb issue. I merely prefer to de-barb the hooks.
I also fish w/ smaller hooks, so there's only so much penetration, barb or not.
That article is nice. I'll have to try that. But this red "plunger" thing works great & would work fine for what was shown in those illustrations.
I never want to leave a hook in, so I'll incorporate the technique discussed in the article as my last resort, hopefully.
