Oh my....   :-X

I saw two pros on tv using these the other night.  They were talking about how the coffee scent attracts fish.  

I was wondering if they contain any caffeine, if they do anglers can chew on them throughout the day to get a boost!    

for those early morning fish

Ive been using these since they came out, in fact I have noticed that my plastics have become mostly strike king. I dont know if the coffee works or not, but I have caught a lot of bass on them from smally on erie to largies all over the place pond/lakes/rivers!

I've also been using them pretty much since they came out, and I to have also noticed that most of my soft plastic are Strike King. I have seen these produce when other soft plastics, or any other lures to be exact, wouldn't on a small farm pond I fish.

Great baits.  I have caught a ton of bass on them.  

Their great. I like that the rage tail line of baits has coffee scent also  

Don't know if its true or not, but I have heard that the coffee smell doesn't necessarily attract fish, but masks any human scent.

Coffee smell or not, they catch fish. They also come in my 2 favorite colors: Black with Blue tail and Green Pumpkin with Chartreuse tail.

4.5" my favorite.
