After listening to one chap extolling the virtues of half hollow and half dacron to stop fish running I thought I’ll give it a go, however it is a great tactic on smaller carp up to say 5lb to stop them running to far , the problem I found was when they bolt up the peg on a snake lake where you are limited for room, it was only when the no 5 section exploded that I thought maybe not such a great idea, when you can ship back fast without any obstacles like bushes at the side and the carp don’t run big it can up the speed, but when you go to lots different types of fisheries I wouldn’t risk it, also with pulla bungs you can reduce the ammount of elastic without risk to the pole.
