Ok i use mainly nickle or brass plain blades. What is the main reason for switching from the two blade colors. Is the silver for clear water and the brass for stained water? Am i missing something by not using the hammered blades?

Whats the advantage of all the different blades?

Colorado

Indiana

Willow

I'm thinking the willow blades look like bait fish and the other two blades thump more on the lateral line.

Sorry for the dumb question but i'd like to get into the blade baits more and figuring out a killer setup on the larger spinnerbaits.

Don 't worry much about blade colors, my favorite is gold, but I fish with silver, gold, copper and even painted blades; in theory silver blades for clear water, gold for murky/muddy water, however it 's not entirely true. When it comes to finishes it 's polished, painted and hammered/diamond, hammered and diamond have more flash than polished because it has more reflective surfaces, that 's the kind of finish I prefer when fishing poor visibility water.

Colorado: maximum thumping vibration, maximum lift

Indiana: less thumping vibration than Colorado, less lift

Willow: a lot less thump, minumum lift, because of being so narrow the blade is great for fishing weedy cover.

Now, forget about what you think it mimicks, it mimicks nothing, nothing in the water swims in a rotation maner.

So that 's for single blades, but there are combinatios:

Double colorado: twice as much vibration, even greater lift

Double Indiana: idem

Tandem: 1 Colorado/Indiana + 1 willow, it adds thumping vibration.

Double willow: as the name implies, 2 willow blades, normally the one on the front is a size or couple of sizes smaller than the one in the back. More thump and even less lift.

And there are even more variations with more blades.

Now, which types you need ? to tell you the truth I fish mostly single Colorado and single Willow, ocasionally I tie double Colorado or Tandems, don 't tie Indiana blades because I don 't even have any.
