Is there a bait Columbia smallmouth will take....

...and pikeminnow won't?

 

Fishing is currently excellent on the Columbia River.  Drop shot with a maxscent flat worm gets hit immediately in 30-40 feet of water.  The problem is I'm catching 5 Pikeminnow to every bass.  I also haven't found any of the 20" bass I know are out there., but caught more 18" in one day than I ever have.  It's been fun.

 

What would you suggest to get me over 20" and minimize time dealing with Pikeminnow?

Wobblehead is what I have been catching my better fish on. I use a Zoom Zcraw and a 1/2 or 3/4oz jighead depending on depth and current. 

 

FYI, I am fishing the Bonneville pool. I catch some pikieminnow on it but probably 9 smallmouth for every pikieminnow.
