Just like to add , as somebody above has said , sometimes you have to sacrifice something you like in a rig and in this case is was the suppleness of a braided hooklink .
I did try various fluorocarbons and monos straight thru but you could hear ronnie & reggie making themselves busy and it was making me paranoid so i was checking the rigs every hour or so .
Although the hookbaits were unscathed (large bottom baits , armameshed and tied to the D with half a paper clip ) the hooklink materials took a battering .
Little chunks missing from the mono's making look like it had been pulled through a mussel bed or something .
They never managed to chew through the hooklinks but it was probably only a matter of time .
The Magic Touch was the only material i found to be fully effective .
Also a pva bag about 6 ft from my rig helped as a decoy
