I finally caught my first walleye on Wednesday night. I just got my boat and I'm still learning. I was fishing early evening behind the windmills 30-38 FOW. I was running a double blade harness with #5 Colorado blades, chartreuse red eyes. I had this rigged to a 8' leader off a 3 oz. bottom bouncer. Trolling 0.8-1.5 with 120 ft. of line out.

Can anyone spot an error to my technique?
I have been fishing there for 3-4 weeks, and just got my first.
I have been using single #3 blades, and just switched it up, and it worked.
I thought 2x #5 would be way too much.

Any questions or comments would be appreciated!!!
Thanks
