Ah excellent Hutch ! .
I worded my original question clumsily which meant that this thread went off at a slight - BUT very welcome ( because I learnt more stuff ) tangent .
I'm very interested to read what you say about mouth damage with Krank hooks , Hutch , as when I unintentionally caught a 2lbish Tench on a barbless Krank ( sz. 10 I think ) its' mouth was full of blood when I came to unhook it .
I haven't had another incident like that again , and I wonder if like some of the published rigs and hooks Kranks are more aimed at bigger Carp ? .
