Not sure about the code blue scent as 37 bucks is a quite a bit of money for experimenting--lol.But i did have some "Luck" with the WR trails end 307.I have seen deer come into this stuff and put their noses right to it.This was early in the year
My friend shot a small buck last year and I took the tarsal gland from it,put it out during the rut and wow,really gets the bigger bucks going.This to me is the best "scent" in the woods during the rut period,and it never cost me a dime
