Im my experience you have to be absolutely sure that the grub is rigged straight with tail down. Whatever brand of jig you use and grub follow the seam down and come out straight. Also, not sure what size the jig is in the pic but if you are rolling lots and already rig straight then go to a heavier jig. By the way, the jig in the pic is a good brand and based on my observations is less prone to roll than some of the other brands.
