Couple things. 1st I hate crank taps too, at least in class. I try to be as nice to my friends and training partners as possible so I try to adjust head-and-arms and guillotines as much as possible to try to make them clean blood chokes. That said in a competition it really doesn't matter.
But about cleaning up your chokes, I think the J Necktie is definitely the hardest of all the head and arms to make a clean choke. With arm triangles and darces and anacondas you can really adjust your arm and body placement to get angles that won't crank them as much. With the J Necktie you're just crushing them with the vice grip and your body.
That's just the nature of the position. Like Eddie said if you like the necktie and the twister you just gotta embrace the crank. In the rules it's technically an arm triangle like the darce, anaconda, regular arm triangle, ezekiel. Those are chokes that also can crank. The J Necktie is more of a crank that also chokes.
