Don't be worried by inturned kickers, 'closed' gape or line aligners, I think that has become a buzzword for missed indication or for using the wrong rig for the feeding situation. I.e. some carp suck and blow, others pick items up, it can be spot dependant in a water, or it can even be individual fish
If you look at a Withy pool rig there is absolutely no 'open gape' at all, yet it is effective.
The front of the hook, the eye, the inner of the tubing is what causes hooking or pri cks in the mouth. To have the line exiting the back flips the hook out bend and shank first. It will work with fish that pick up hookbaits and the hook pri cks the lip, but not suckers and blowers.
