Locator jig

[Spoonminnow]

Just a few suggestions:
1. gotta find them first
I'd be lost without my old cheap b&w Lowrance sonar. I tells me bottom depth/type/configuration/solid or soft/weeds if present and most important : FISH! Baitfish are usually the first that show - the more the better. Once found, I anchor and cast, cast, cast making sure the lure is at the depth the fish are. As usual, the larger the water, the more difficult it is to find fish - ANY FISH!
Knowing a water means knowing the above which also includes seasonal fish locations.

2. A lure's action-profile matters big time!!
That said, a specific action-profile moves a certain way and is chosen for a few reasons. Example: different spoon shapes have different actions and drop at different speeds. (Compare a Hopkins to a Silver Minnow for example.)
Another example: A curl tail grub has a much different action than a grub where the tail has been removed such as these examples:

The curl tail flutters and flaps and it is retrieved at a steady speed; the no-tail is twitched & paused and can be worked slow and in place. Both are excellent all species / all size fish lures, more versatile than most.
Along with the lure's action-profile, overall lure weight makes a big difference! A 1/4 oz. lure is worked different and moves different than a 1/16 oz. General rule: lighter for shallow water/ heavier for deep.

3. Cold water vs warm water
Fish do bite under the ice, being cold blooded, but only using a vertical lure/presentation. The range of warm-water lures and presentations is huge! It's just a matter of chosing any of a few hundred lures that can get it done.
Note: sonar does initially find fish, but lures are the ultimate fish finders whether in open water or near weeds.

Got a few more suggestions, but don't want to bore more readers than I have already,
(... though sometimes more is best)
