one thing about adding anything to your plastic baits is I have never found anything that I really like is nothing is seems to be natural though they have a great many names on their stuff. But is it actually the real McCoy like per instance crawdad nightcrawler Schram and many other flavors. If you have smashed up a crawdad and took a whiff of that. I believe it would be quite different. I know for sure nightcrawler is very oily and they do have a odd smell like I've told you guys before the one I would truly love to have in Lake would form is Berkeley's crappie nibbles. We Thrown the nibbles in with my plastic baits and locked the sealed bag and left him for quite a while. They will take on the order but not like if it was actually in the plastic. We never ever go fishing without nibbles I buy that stuff by the case and we use them on everything including crank baits, even if I'm fishing plastic worms or what ever.
