I wish I could go Thursday, but I cannot.
So, I will try to help here.

First, I would say that you should go and pick up a trolling book from Cabelas, Bass Pro, etc.
Precision trolling is good.
This will give you the correct running depths for your rigs, whether for sinkers, crank baits and various divers.

This link will give you a better idea of what depth you are running with in-line weights.

I would also say you should get some inline weights from Cabelas or elsewhere.
2.0 OZ in-lines are usually about right for any western basing fishing as the depth rarely exceeds 30 feet.
Running bottom bouncers skews the depth the bait is running because of the extra drag the hardware causes. Besides, they should really only be used when "bottom bouncing"
Here is a good chart. Print it and take it with you.

The next step would be to use in-line planer boards if you are not using them already. They will take your bait out to the side of the boat. They are about 55 dollars a pair at Cabelas, or Bass Pro.

With all of that said, a standard in-line weight setup for the western basin is:
2 OZ inline sinkers with a 36 inch leader running 35-40 feet back behind your planer boards. You can use crawler harnesses this time of the year, and move to spoons in a few weeks. Run between 1.8 and 2.3 miles per hour.
Adjust your depth to just above (5 feet) the fish being marked on the sonar using your reference book. Walleye feed UP.

Good luck!
