Very good advise on the videos available!! One of the best pc's. of information I have ever gotten came off the show The Next Bite, they were using the minnow worm harness spacers from Bass Pro Shops and they were catching alot of fish, I have always been a believer that the main attraction on the worm harness was the blade and I still am. They were also using the XPS Hatchet Blades which they only casually mentioned but were plainly visable in the show, and they turned out to be the best thing that I have ever bought or seen on the TV for walleye fishing and they weren't even plugging the blade but the spacers. The blades are no longer available but the spacers are, which I do not use very often if ever. I managed to purchase a couple of hundred blades in each of the colors that produced fish in numbers while they were on close out at 3 blades per pack for $.99 two years ago, so I am set for life on those blades.
