Lick and stick for me and not to much pressure when I fold the nugget. Iv cast out at distance to showing fish and had a take within minutes on several times as has my mates, also done the rig in a tall jar with ice cubes and the pva has came away from around the hook. Imagine the force of a 3 1/2 ounce lead smacking into the water that would also help in removing the PVA. I would have to hire out the Hubble telescope to see the form nugget hit the service 😂 When the chod rig ( don’t hear much of that rig now ) came out I thought il give that a go didn’t use a nugget around the hook and had the occasional fish on it, then il reeled in one time and the hook had pierced the lead core so a nugget was used after that.
