The Senko is my "go to" lure under most conditions. I fish it slightly differient. I want to maximize the natural wiggle is has on the drop, so I let it fall on a slack line. If I don't get hit that way, I dead stick it for 10-15 seconds (drives me nuts-but pays off sometime). I have no luck with it at all with a current. I normally fish with a 5 incher, but if things get desperate, I have a supply of 4 inchers.
