Esp anchor rig tube is my favourite. I usually thread 2 foot on (easy with the esp stuff) and then stretch it once its one the line, making it thinner and more supple and it stetches a long way, up to 3 foot. This does damage the line though so once i have stretched it i moisten the line and slide the tubing up a good 6 foot and cut of any damaged line! Hope this helps mate.
