Hi Sirmo;
I've seen where some guys do add minnows to their jigs.
I believe it's more of an experimental thing. If one thing doesn't work well, then try another technique.
In order to know the truth as to if a particular technique works or not, you'd have to know for sure that there are fish down there to begin with, then you'd know whether they like what you're presenting or not. What they turn on to this week might not necessarily work next week, got to be ready to try something different till you hit the hot one.
Myself, last year I used minnows exclusively as they worked well and I had no reason to change up.
This year, am still waiting for the bite to take off, been throwing everything out there with absolutely no bites.
Have started hearing spotty reports of a few being caught (Central Fla).
Heading to "East Lake Toho" (Kissimmie-south of Orlando) Sat morning, been dying all summer to get back to pulling in some slabs.
Good luck to you !
