Like Spoon said it could be a lot of factors, I hear more and more about spoons for taking Eyes this year than any other year. It sounding more like a steelhead spread then an eye layout.

The walleye have been changing the rules on me and I didn't get a copy. I used to rig 4 bouncers and crawlers at the back and put hot-n-tots on inline boards to the side.
Now it's 2 bouncers out the back, 2 dipsys on the sides with spoons, a j-9 rapella with rubber core on one board, a spoon and rubber core or mini disc on the other board, and a lead core line (4 colors) up the gut. I troll between 2.1 and 2.6 MPH, this has worked ok for me in the late June and July, mainly in Buckeye waters due east of furmi or by west sister.
