yo-zuri crystal minnow help....

My Gander MTN has alot of yozuri crystal minnows for sale, all sizes 50% off. most of them say "floating" and they don't give a dive depth. They have lots of colors.( i am not familiar with using plugs other than the occasional x-rap)

Are these worth getting for pier use? Will they catch the macks?

For throwing on the pier you would need sinking. The floating will dive for a short period when you first start retrieving, but as it gets closer to the pier it will just come to the surface and you will stop getting any action from the lure.
