For kokes I use a couple of different techniques:

*Troll chartreuse or red wedding rings tipped with white corn behind pop gear or Ford Fender. (use a small rubber snubber, too) If you use leaded line and have two or more guys fishing, experiment with depth. If you have a downrigger, put a small thin-bladed spoon(needlefish, dick nite) on it all by itself but troll it among the popgear. A big koke on an ultralite rod with no popgear is a blast.
