Both point of view really. Barbless hooks were not invented for large fish. The match lads started using barbless in the name of speed.
I think, as do others, that they cause more damage to a large carp than a barbed do and being as I dont particularly like sticking a hook in any animal I like to keep the damage to a minimum.
Im also of the opinion that clubs/venues etc that strictly enforce a barbless rule are shortsighted and in the case of clubs usually run by matchmen, venues just by people in it for the money alone.
The 'no nuts' rule doesnt sit well with me either. A blanket ban aimed at the percentage of anglers who'd be stupid enough to use too many or use them dry, if people are stupid enough to make such basic mistakes then that percentage shouldnt be fishing for carp.
No shelf life baits either, dont get it, most shelf lifes are good baits just with a capfull of preservative.
All these nonsense rules would really put me off a place, and if someone asked me to reel in to see my rigs??!!
I go fishing to fish and relax, not be monitored like I was in school. Each to their own tho..
