I will switch over to using minnows on spinners later in the season. Late Sept/early Oct timeframe. This time of year it’s crawler and leeches for me. Just a lot easier to keep them alive. That’s alive in the boat and between trips! But you can definitely run minnows on spinner rigs, and a lot of guys do.
On a side note. I have had terrible luck running spinners so far this year. This is one of those years where you need to slow down and finesse fish with a lindy rig…or even slower by anchoring up and bobber fish them. The fish have plenty to eat and you need to force feed them some desert.
