Hosel rocket is great but I prefer worm burner.

As for curing shanks?? EASY MONEY. This golf pro taught me a sweet tip. When you get a case of shanks. Don't change your stance or swing!! Instead pick a blade of grass other small item a half inch inside the ball (toward you) and zone out the ball, just ignore the ball and swing through your new target.
I also hold the club horizontal with standard grip and focus on the toe. I spell the alphabet until I can feel the toe instead of the shaft. When you shank you are swinging the shaft not the head and hit the shaft (hosel) on the ball.

TRY IT!!
