At the Gite we visit in France, there is no hard and fast rule on barbed or barbless hooks. I have always used barbless hooks for my carping, as most fisheries over here insist that you do and I personally felt that they did less harm to the fish.
Whilst over there last year I was using barbless and lost a couple of fish. The bailiff, a really nice guy, suggested I used barbed hooks. I didn't have any in my bag but thought I would use them this year for a change.
I felt much more confident using them and only lost one fish, a really big one, right old scrapper that slipped the hook on the way to the net. I was gutted, but feel quite sure had I been using a barbless hook, the fight would have been over long before it actually was.
I didn't have any forceps with me, but the bailiff lent me a pair, and these made removing the hooks a doddle, so much so that I purchased a pair of my own as soon as I returned.
Trying to remove the hook, even a large size 4, with wet hands can be hard work. Forceps make it so much easier.
I am definitely in the barbed camp now, just as long as you have the necessary tools to remove them properly.
I have read all the arguments regarding barbed and barbless. I'm a firm believer that all of the damage to a fish's mouth is done by the anglers ham fisted attempts to remove the hook, rather than the actual hook hold during the fight
