advice on plugs i just purchased.

Hi i just got 4 plugs from ebay and was wonder are they to big for shore plugging for bass they are all.

190mm in length to me they look very big but dont know enough about this form of fishing.

they do sound a bit big for bass, but perfect for pike. even a 5 pounder would take a plug that size. maybe you could trade them with someone?

are they jointed ?
