I agree with Josh's advice. My V89 opens as good or better than any eliptical I've ever jumped (including Spinettos). Let the nose hang evenly without rolling or pushing it in. If you are loading heavily all elipticals are very sensitive to slight body movements during the deployment sequence. Also helpful is keeping the d-lines from both sides next to each other in the center after flaking the pro pack. If they get seperated it seems more likely, in my experience that the canopy could open unevenly.
All that being said you will probably still get an off heading opening on rare occassion, it's an eliptical for crying out loud. With experience it's a simple matter to minimize thru packing, body position, and monitoring and reacting to harness feedback during deployment.
Don't forget to always track for adequate seperation and be prepared to use rear risers right away. You never know when the other guy is experimenting with a new packing technique
