I de-barb on the water....and only where required. With trout-sized patterns, I have never really found removing the hook to be a struggle. Especially with forceps.

I do not buy in to the damage issue. I feel a barbless hook moves around while playing a fish much more than a barbed hook. Causing just as much damage in many cases. A small barbed hook stays put. Just my thoughts.

I do however feel with larger hooks the damage can be an issue. Mainly do to the size of the barb itself.
