I've been crimping barbs down for years, not only for the safe catch & release of the fish, but for safety of us fishermen as well. I do it religiously now on all my hooks, especially trebles, with no detrimental effects on my catch/landing ratios. Anyway, the way I look at it, what's the big deal if I loose a fish anyway? It's not all that important to me anymore to land everything that bites. And I do not find any draw backs to Texas rigged Senkos with crimped barbs. Sure does make releasing the fish so much easier!
I've gone a step further as well and that is removing the trebles all together on my lures and installing single hooks (again, with the barbs crimped down). I thought for sure my success would diminish. Not so. Single hooks are every bit as effective as trebles.
One of my favorite bass & lake trout lures are blade baits. This can get real costly, real fast when using trebles (if you fish them right). So, now my blade baits (1/2 & 3/4 oz.) have no hook on the lead hangar and a barbless VMC In Line single hook on the back:
This is the lure I took my gold pin C & R lake trout with last season. I posted a picture of this brute in the "Trout" forum.
