I agree Nick the baits you mention have a shelf life and to just use common sense, but the tubs of pop ups has no written date who knows how long they been on the tackle shop shelf, especially now with some tackle shops closed, then we buy them and keep them for “years”taking them to the bank on hot sunny days
Framey I think the modern hook baits are more than Lures they give out food signals, and it’s the food signals I worry about maybe going off and us not detecting it...or it could be that I’m overthinking it lol... but I’m happy to bin them and feel confident with a new batch.
