I usually buy Mike's shrimp oil and have for 15 yrs., recently tried the Smelly Jelly shrimp and caught fish on that, I don't really think there is that much difference in them its more just to cover the human scent and any of them do that fine.
I do have a question, does anyone know if heat will spoil this stuff, I've had times when my vest was left in my truck on hot days and have often wondered what if any effect this may have. I have thrown a bottle or 2 out just because I wasn't sure.
