I am curious about the viper spoon harnesses as well. Hope to hear from someone who uses them. I like to run spoon and I like to run harnesses. These seem to be a hybrid of both. And yea, I think they are around 8 inches long. I've seen them used on YouTube with live crawlers and Berkely gulp type artificial baits for eyes on Erie but not tried any myself yet. They are pricey and have limited amount of colors, but I would like to try them.
