Loop knot jigs will almost always stay horizontal in the water unless the jig is tail heavy and that’s about impossible .
It’s the only knot I use and you should experiment with it and discover its simplicity .
It ties fast and is built to last and the only down side I have ever encountered is if you have cheap jigs and the eyelet isn’t closed up tight .
The upside is you ain’t never seen a jig look more natural and never have to adjust the jig on the line like you have to do with clinch knots and Palomars as well .
I use it always and vertical jig constantly and pitch and drag and etc etc etc
