I was reading some older threads on running/shocker vs bolt / semfixed rigs and it seemed a lot of people prefer running rig with slack lines due to no resistance. I've also read elsewhere that when fishing in the margins using no lead and going straight to the hookbait with your mainline fishing slack lines can be very effective. Surely this type of rig would cause even less resistance to the carp and can provide some very good bite indication and on certain waters where the carp are wary of leads and such this could be very effective. I would just like to hear some other peoples opinions on this
