In regard to the tail orientation, don’t over think it. I know it doesn’t look natural. However, look at 90% of the fluke molds, horizontal and proven fish catchers. Boot tail swimbaits, not natural looking but proven effective. I’m not saying a vertical tail won’t catch fish, I’m just pointing out what that horizontal tail profile can do and that’s movement. A fish isn’t going to inspect a bait hard enough to decide if its tail looks natural. They are going to see a bait fish profile that is struggling and is an easy snack.
I too have the 3” silver fish and love it. I have caught everything from crappie, bass, trout, and catfish to saltwater fish like flounder, trout, and striped bass. A slight rod tip twitch dead sticking in current, to vertical jigging causes the tail to quiver and trigger bites.
