Wrapping a whole slice of bread around your line has been one of my advantages for the last 7 yrs for taking Carp of the top.
Only certain types/brands of bread work ie Warburtons thick sliced being the best as most are too dry or too thin.
Not having read the article I can only comment on how I will tackle up.
Carp rods are too heavy for this so I will use a Heavy feeder rod with a 2 oz tip on, 10lb Fireline and a size 2 barbless hook. Notice no controller!.
Take a slice of bread and take the crust off.
Now fold it in half but do NOT flatten it and put the hook in the top inch, with the hook point showing, with the line running the length of the bread.
Roll the bread around the hook shank and line and pinch the bread firmly around the hook shank and lightly at the other end to the line.
Dip the bread in the water for 1 second and cast out.
You should find that the bread will weigh about 2-3oz when wet and will cast a long way hence the need for lightish line and a feeder type rod.
I use this method at night when big Tench and Carp are feeding right out and detect bite by holding the line in my fingers. Doon't worry about moving the bait to keep a tight line as the fish do not seem to care in the middle of the night!.
Up to now I have had a few good Orfe 6lb 4oz, Chub 5lb and a lot of Tench to 6lb oz8 and Carp to 16lb and 2 Rats ( I kid you not, they fight very well)using this method.
What makes it funny I used to be laughed off the lake at first as they all said Mixers worked the best till they heard of my catches!
