I have some of these very large swimbaits, not sure brand name (picture attached). I wanted to see what’s the best way to fish these? This one sinks very slowly but has great action while dealing it in or quick jerk movements. I’ve never really fished swimbaits before. I’ve tried casting along shore, casting from shore to deep, deep to shore, and out in the middle of lake. Nothing has even followed it. I’ve even tried just reeling it in, quick jerk let it sit for a second all the way in. Any help or are these just a bait you cast and hope that someday a big bass will take it?

That's a "small" swimbait. Large would be 10 inches. A two pound bass in the mood would not balk at striking that swimbait. That particular style bait is called a "glide bait". All swimbaits are fished VERY slow, in general, sometimes even deadsticked, but the glide bait isn't (dead-sticked). The slow sink rate is intentional as the lure can be hit on the way down, just like a jigging or flutter spoon usually is. There are several retrieves to try with a glide bait. Search that on youtube and you'll find some videos. A good one is S-waver glide bait fishing

This one is 8 3/4” I guess I need to buy bigger baits. LoL but thanks for that information I will look up more videos on this.

With that color swimbait, I'd seek out a clearer than average body of water (at least 4 feet of visibility--you won't get any interest if they can't see it) with a good striper or larger hybrid striped bass population.
I'd start at the clearer parts of Texoma.

A bolder color swimbait, like bone or green hitch or green back shad would do better in more of the lakes around here (especially those with a healthy gizzard shad population) Certain times of the year, baby bass and blue gill colored swimbaits will outperform.

For the most part, fish them slow with intermittent pauses and twitches.

There are some, like the Bucca shad that perform better retrieved faster.
