I'll never do this. It's not like every time you go fishing, you hook yourself. I catch a lot of big fish, such as Grass Carp, I would be pissed if I fought one for an hour on ultra light only to loose it because of no barb and then see it die because I wasn't able to help it back into the water properly.
I caught a crap load of native fish for my 500 and few other tanks. The few fish that got messed up a little bit from the barb, all healed up rather fast. I realize there are times when it can get infected, but anything that has an open wound with or without a barb can still get infected. I'm sure the fish can still feel the sharp hook penetrating his face with or without a barb.
If I did do this, it would be for the challenge but on small fish only. Fighting big fish and not being able to help them till they can swim off on their own is not a good things in my eyes. It takes me 15 minutes sometimes for me to help a fish get strong enough to swim off and not float belly up. Big fish build up lactic acid which can kill them very fast, especially in the hotter months.
A lot of times if you embed a hook deep inside you, your going to get it checked out anyways. So you will loose a day if fishing. Some folks may not be up to date on shots, they may get worried about infections and want it cleaned up, etc.
I've been fishing since I was 9, been hooked once in the lip and that was because the other guy walked behind me when casting. It was a small top water fly, dull and semi rusted hook.
Do what you like. I respect your decision, though I may not agree with it.
