fender22,
Depends what you are chasing
Bream - up to 3 inch shads or wiggle tails
Squire/Sweeties/Parrot - Usually prefer the 5 inch plastics, in some of the deeper water in the bay even give the 7 inch a go.
Just personal preference in the shallower water, find gulps especially the in the shad style are not as effective as other brands such as bass assasin, zooms or squidies, I think this is because they don't have as much action and with a smaller strike zone this is very important. On the days that it is very quiet gulps can always give that advantage with the strong sent that they have.
Also might help you out, on overcast days or murky water try to stick to really dark colours or really bright colours and on the sunny days or clear water try more realistic colours.
This is all personal preference, also try and go as light a leader as you can
