Asymmetrics are good for that type of shot, its just that MOST prefer symmetrics due to them not being as jumpy off the break. Someone like me, who tracks high, has little tilt, and a higher speed, I can use asymmetrics on a crisp backend shot as my style does not lend to much backend in the first place. Of course, no matter which ball(s) you pick, you will need someone who can find your PAP to properly drill an asymmetric ball.
The 2 balls you have picked are really good, but, they are both polished, which mean if you ever hit much oil for whatever reason, you would be stuck as both of them will skid in oil no matter what drill. An original Rule would probably be the better choice, and if it hooks more than you like, a simple surface adjustment will take care of that. The Heat would be a great second ball to go to when the lanes break down!
