hi,
all tides are fishable, just the smaller tides mean you can fish longer as stated by spirit. best rigs i have found are two hook running ledgers, i'll try and add a sketch.
i have also switched from aberdeen hooks and now use size 6 carp hooks which will land the smuts which take the same baits intended for the bream. best baits i have found is lug and squid. put say 1/2 a lug on the hook then a few seperate small pieces of squid, tipped off with a longer thin piece. bream will strip hooks bare quite quickly if only a single bait is used. if you have a bite and miss, dont retrieve but drop the bait back quickly and they will come back.
here is my best sketch, leads can range from 2 upto 10 oz, but this rig always gives a direct bite on the rod tip.
if you have a chart plotter just fish the outer-reef when you can and the inner reef when its running too much. if you haven't just fish near the line of boats you will see at weelends!!
you can fish straight through on neap tides and 1 1/2 hours either side on biggest ones.
