I say it can't hurt. IMO It seems more effective in colder waters. This was my 1st year using JJ's and Megastrike and early in the year (Early Spring) I could see a clear difference between my bites in colder waters when using scent. As it became warmer it seemed to make little difference. I have 2 more tournaments up north and both products are going with me.
Let's hope they make the difference
