The reason I bend them down is that I'm a CPR fisherman primarily, keeping only a very small percent of the fish I land for the table. (I much prefer eating salt water fish than fresh.) So, the barb-less hooks make releasing fish soooooo much easier! And getting on in years, it's probably easier for me to make a mistake and hook myself, instead of a fish! Barb-less hooks make that kind of removal much easier as well.
