don't let anyone, especially youtube tell you how to fish.
finding what works best for you is part of the great adventure that is carp fishing, it is ok to take on board the advice doled out at the carp.com pulpit but i bet none of the die hards on here take the info gleaned and use it undiluted.
i'm not saying "don't ask for advice" because that would be stupid, even Dal, nick Tim or i have asked questions in the past, its how we learn.
most of us are 'time served' but we can still learn from others, i have 50+ years from canal for gudgeon to carp but you should have seen my face when i first saw the bungee rig a couple of months ago
bailiffs are only good for one thing and i will take that with a pinch of salt and that is bait info.
i will use rigs from 3" to as long as 2ft depending on the lake or method that i am using at the time.
enjoy your learning curve and tight lines
