Its the taste..... I think it gives you a better tase.
I wrap with twisted wire and its pretty cool. You need to twist it up more than the photos Ive seen above though. Put a cotter pin in your drill, feed the wire, doubling the wire and make a piece as long as your arms can handle it, then, while keeping preasure on it, start the drill and keep the drill twisting until it breaks off. It will break off at the cotter pin end every time. This twist will be so fine that most people will have to look close to see that it is two wires twisted together.
Do it.... Its reall Cool !!!
