When I don't pinch down barbs or tie on barbless hooks, I find that in some cases that releasing fish takes longer than without a barb. I don't worry about losing fish on barbless hook because as long as you keep tension on the line, there shouldn't be many thrown hooks. With barbed hooks, you can usually get away with slack in the line while fighting fish. I think that in most cases you will be fine with barbless or barbed hooks. Hook removal is no doubt easier with barbless hooks though.
