Everyone of those jigs is a killer, although I prefer not to have the weed guard and do prefer twist tails.
Tip them with a minnow if you are going to troll and go .08MPH with your rods separated covering as much water as possible. You'll catch fish.
Eliminate speed as an issue and get a GPS app for your phone if you don't have one already. The slowest speed setting doesn't reflect true speed once the lightest breeze blows or change in chop of the water.
Not a problem if you can't keep a constant .08, just keep it >.75 and <1.0 MPH. Some days one side of the interval is the ticket, others vice versa. The nice thing about bumping between different speeds is the correlating bump between different depths. If you pick up the first couple of fish of the day while you are speeding up towards the 1MPH mark, you can assume you starting out fishing too deep and you can make the adjustment, etc.
Good luck.
