I have found them to be real good on certain lakes. Berlin Res. is one of them.
I've caught some pretty decent eyes trolling there with either a perch or chartreuse w/orange belly. The go to (or at least starting point) anywhere else for me is chrome/blue. When in doubt, troll everything you got for 10 min. each till you find what they want. Wally Demons work pretty well too. They are kind of similar but have a single chrome bearing mounted in the lip.
I caught my first 10 pound eye on a the multi colored one. it was yellow, blue, pink, orange, all different colors, clown colored litterly, no the red head clown, they catch fish really good, I caught other walleye on that same bait before my bro decided to lose it.
ohhh yea i love perch and gold i want to try the new joined ones but have not got out to buy them. i troll and cast them with great turn outs i have cout smallies large mouth walleye sauger and northerns on them they are a great lure .
