Sometimes I would fish the senko like Jerbait....

 

I have caught one fishing it like a jerkbait.  Maybe I am messing up fishing it like any other worm.  Probably not slow enough

I have more Senkos (and other stick baits) than all other lures combined.  The advice about going slow is the key.  I tend to be impatient.  It always seems that I catch my fish on Senkos when I am distracted and not actively working the bait.  When I force myself to slow down, that's when I do my best.  A lot of times I'll let one drag behind me as I drift fish in the kayak.  I catch more that way than I do the one I am casting.
