From the shore i would go for a Fiiish Black Minnow, 12g .Bass usually hang around quite close in ,so you dont need to cast to far. For the Mackerel you wont go far wrong with a Savage Gear Seeker ISP in pearl white, you will catch Bass and Pollack as well if they are about so a good all rounder.
Retrieve wise i would just mix it up if you can, fast, slow, pause , sink and draw etc,and bring the lure right up to your feet before lifting it out. Bass have a habit of leaving it till the last minute to strike, First and last light are usually quite productive. Enjoy your hol
