Johnson Fish Scales and Crappie Nibbles

[MSUFisherBear]

The cold front that rolled in today got me to wishing it a) hadn't happened right before the weekend and 2) thinking about tackling cold fronts for crappie as spring rolls in. That got me to thinking about jig modifications and what to do to possibly entice one of those sluggish paper mouths to strike a jig. Alas, we come to the topic. I've toyed around with crappie nibbles in the past for this vary reason. I use a baby medicine syringe and inject them in the business end of a tube. Sometimes they seem to make a difference and sometimes not.

I was wondering if anyone has had success with those in the past and what other ways you may have used them. I also have wonder about the Johnson fish scale attractant (if anyone has used it/had success). Is the stuff able to be injected like I do with the nibbles? Do you just smear it on? Does it work or is it just a gimmick?
