I’m sure it would work. There are aggressive bites where nearly anything will work.
There are also times where you need a specific size, color, etc to trigger a bite.
I always want the diversity of offering, including live bait. I still fish rippin raps all the time without any meat. But, if I run into a really tough bite, I want some live bait.
I guess I don’t find a scoop of minnows to be that much of a hinderance. The benefits outweigh the $3 and carrying the Engel.
Also, I can keep minnows alive for quite a long time in my cooler with aerator. There are many tricks. I’ve fished multiple days on a scoop of fatheads.
I also cut heads off of dead ones and throw them in a bait puck of the freezer in my garage beer fridge, as mentioned above. Don’t always need a live minnow, but you’ll catch more fish if you have a second dead stick with some live meat on it (I have in my experience, anyway).
To each their own, but if you’re going through the trouble of everything else why wouldn’t you want to maximize your odds?
