120BPM DBX Picking?

I'm trying to accomplish DBX at a "relatively high" speed. Ideally, I'd like to play music that requires escaping after both up- and downstrokes. I can make this go a little faster towards 130bpm, but the pickstrokes become a bit limited, not fully making the motion. Should I work with this, or let this go and focus more on my DSX (220bpm) and then try learning a helper motion for escaping after upstrokes?
