The Volatility has a quick response cover and is really forward off the end of the pattern giving it more of a hook stop motion. Reality is much earlier with a more rounded continuous motion but probably won’t see much action on typical house conditions except for speed dominant players. That said the Volatility wasn’t very popular and there are other strong Pearl/hybrid asymmetric with similar motions that are probably better.

The Reality comes in at 2000 OOB.  If that is the ball with the most continuation downlane.  Why not polish it up to make it cleaner through the front part and a little more angular if that is what you are looking for?  You could start by taking it to 4000 first and if that is not enough, add some polish.
