Moonshine Shiver Minnow?

I keep watching fishing programs where guys are using these baits to catch walleye year-round on lakes around the country.
1. Anybody (casters) have success using these baits on our Erie-eyes?
2. Do you have a particular size that you prefer?
3. Do you have success with them in the summer?

I use them once in awhile if I go out and want a break from trolling and find a bunch of fish on the bottom. About four weeks ago I went out for one of those trips and came across an area that had bottom marks all over it, I decided to Shiver and play around. On the first cast I caught a 14" walleye, at on time I made three casts and caught three short walleye, ended up catching around 30 walleye but only 2 keepers, but had a fun day just doing something different. I was using the largest version and the fish would just hammer the bait. From past trips I can tell you that if there are Sheephead in the area they love them also.
