Hello mate,
Once you have tried them, you never go back. They do vary however. Lug need a blunt needle - point rounded off, and these can vary in thickness (wire gauge) and length. Big lug are better on a thicker / longer needle. By the way, put all bait onto the needle at once, ie 5 or 6 lug at a time, before inserting hook into hole on other end and sliding over hook.
Ragworm require a sharp needle - the blunted lug ones are no good.
Tight lines,
Mart.
