few of the best times to increase the chance of catching zander when i used to fish for them ,westerly winds, low light with cloud cover,just before dark,just after dark, coloured water, when its rained or raining,moving water, fish a stretch straight after a match, , least amount of resistence on your rigs as possible, sit over your rods and unclip line as soon as you get a take and feel the fish by hand , fish the margins , fresh killed bait 4in long on a vic bellars double on a home made trace use tube sleeving, oh and be quite , hope this helps it worked for me over the years
