best bet for the smaller (12"-17") wipers is deep holes that correspond with current. The smaller ones stack up with the white bass in these spots waiting for bait fish (mainly shad where I've fished). They are generally in isolated spots so if you can find them, there are plenty. I haven't heard of anyone catching one much over 4lb though but a 16" wiper puts up a good fight.
Flashy stuff that looks like what they are eating is best bet for jigs.
