I used to use soaked hookbaits and for the first couple of sessions not long after i put them in the container, i got results on them. But after the weeks went by i couldnt get a bite on them. I think that they were too over flavoured so i dumped the lot.
I would only use them now in extreme circumstances when struggling for a bite or in winter when using singles but i wouldnt have them soaking no longer than a week. After that i would dispose of them and put some fresh ones in.
And i wouldnt use soaked pop ups either, cos after a few weeks the buoyancy would be effected and they sink after a while and you end up fishing with a bottom bait instead of a pop up.
