Ok,I'll nibble Philip,when float fishing,or using a bait covering the hook,self booking isn't really an option,ie your not going to be able to use a very buoyant float to set the hook,or enough lead,which let's be fair would probably need to be 1.5/2ozs minimum,so struck we must,also many species don't get caught as much on self hooking rigs,chub, roach,rudd,dace and perch,match anglers use eyed hooks for carp,barbel and bream,either with hard baits,or feeder vor lead rigs that need it,it's not simply the go to method that it has become for carp anglers,who use hair rigs or variants of it for everything,it is only a method,a good one yes,but not the only one in the book.
