The preserved minnows are likely a waste of your money in my opinion.
never have got much of anything in these parts to bite them when I tried them , even the catfish seem to avoid them .
the garlic fire gel stuff is way better than the fireballs and the berkley gulp brand crappie nibbles trump both of them most of the time.
I slide my nibbles up onto the bend of hook tight to the body and sometimes put 2 on to cover the entire hook for 2 different reasons ...
1 it makes it somewhat weedless if you are light handed and the stuff you are putting it in is thick and snaggy
2 it adds more scent to the water and its more visible.
and in some cases I use slab sauce alone or in conjunction with other scents too ...
p.s. if there is any hope for the preserved minnow you need to put a jighead on and use it like a plastic body ,run the hook thru its lips and or worm it on and let it follow the jighead , hooked thru the back wont likely look right in the water for sure .
