I started targeting them them last winter, after a good decade or so of fishing for largies under ice. Quite similar, maybe slightly more finicky, unless there are schooled up, they then tend to get very competitive.
For the most part, I use a Yo Zuri rattle n vibe, seems similar to the chubby darter, though I don't know if yours has rattles. Have caught them on small jigging raps and mini kastmaster spoons as well, but the Rattle n vibe seems to perform a lot better for bass.
One of the things I found, is that both species seem to often cue in on a given strike zone. For example, I may find them in 25 feet of water, but only get hit in the 18 to 23 foot range. Anything out of that zone can have them looking, but enter the zone and it's almost guaranteed to work within seconds when they are biting well.
I find they get very aggressive on some days, and super finicky on others, where you'll need to work them for a few minutes to get bit. It helps to have decent ice and snow cover, both bass species get very spooked on thin / clean ice, especially in clear water, despite me hand drilling and staying as stealthy as possible.
I don't spend more than 5 minutes on a hole without seeing any fish, just keep drilling until I hit them.
Lastly, once you hook a smallie, they tend to run up towards the surface a lot more than largies under ice. Maybe instinctive to jump, at times you may think the fish popped off, just keep reeling.
Good luck!
