I plan on using a donkey rig with caffeine shads this week. It will be the first time I'm using it. Should the shads be the same color or have folks had success with using 2 different colors?

I use two different if I have them available. I also use the 4 inch on the front and the five on the back.

I like to use the same color and then modify one of them. Usually I use a scented red marker to add some wounding type marks. I am sure if you dyed a tail or something that would work great too though. 

 

90% of the time they choose the modified one in my experience, even if it is in front! 

Scented marker?

Spike-It sells markers that are scented that you can use to draw gills/wounds/anything on your soft plastics. You can get pretty creative with it on flukes. 

Wow! That's pretty cool!
