Hi Hareball,
Yes ... they have done a good job with the scents, shapes and colors.
They are also running a nice special. Two (2) packages usually costs about $14. They have a $5 rebate if you buy more than $10 worth of stuff. You can fill out 2 rebates per day. Also, Sports Authority has a 50% discount going on now on some of the packages.
So, people use 5" glo shrimp with the corresponding scent, etc. The scent is suppose to last longer than if you soaked bait or a lure in bunker or shedder crab oil (which I almost always do).
I have a ton of packs in different shapes, sizes, colors and scents but I seem never to use it. It has become backup if I ever run out of bait. Many folks have good luck with it.
One other good thing. It is biodegradable.
Thanks,
Ed
