That I do not loose as many fish when my plugs have hooks with barbs on them.
One night I lost 5 fish in a row that were hooked for different lengths of time, all on plugs with crushed barbs. Then I caught/landed one bass, that plug was a redfin with barbs. Now its possible that the Bass I lost were hooked on the outside of the mouth (I think Blazin420 had a few of those one night), but there is no doubt in my mind that on two separate attempts to go barbless (years apart) that I lost fish because I had crushed barbs and there was nothing else I could do to land those fish.
If I get into certain "bites" i will crush them at that time. I was into a bunch of bass in the 25"-34" range this year, after catching 2 I crushed the barbs and landed 8 more without loosing any. Or when catching a lot of blues I will crush the barbs.
But heading out for my walks I will go fully armed with barbs
