I'm aware of that, the extra weight would be for noise purposes.

Gotcha ... if it's noise you are looking for I would try this.  Google:  Cabin Creek "Click-it" Drop Shot Weights.

 

For the record I did use these last year and didn't find it made a whole lot of difference.  My opinion is that the clacking draws attention to the weight.  If the leader length to the hook is too long it might have them overlook the bait more often than not.  I am convinced some of the bites I felt was them taking the weight and not the baited hook.  A shorter leader might make a difference.  Intend to "experiment" with this more next year.  

 

 

Sounds like you have sufficient water clarity. Try drifting with a shorter lead on your DS. Use a small (size 1 or 2) EWG worm hook for the plastic, so that you reduce snagging. You will probably have to use a heavier weight to keep your sinker dragging bottom. And use a bait rig type sinker, such as the Gapen Bait Walker, or one of the longer pencil shaped "bottom bouncer" types - again, to reduce hang ups. 

 

You might also want to take a look at controlling your boat by "slipping" the river, as opposed to drifting right along with the current. Another Gapen technique.

Very little current where I fish, so I don't understand what is meant by "slipping" the river.  Could you give a little more detail on how to do it?
