This is strange - I agree with ALL Stuart says.
I also think that barbless hooks damage more fish than barbed and I have caught countless thousands of carp in my life.
I totally refuse to use barbless hooks, even on waters that demand that you use them. I've had a couple of stand up fights with fishery managers in the past.
Modern hooks are actually quite a bit bigger than the hooks we used in the 60s, size for size. Most of my barbelling these days is done with 8s and 10s Big T Raptors and 12 Drennan Super specialists for small baits.
I my opinion, barbless hooks should be banned!!
If you do leave a red mark with the hook, give it a dab of Kryston Klinik. Something every caring angler should have in his bag.
