I set needle up/down based on what I'm working on - most often down. For Cruise, I think I have mine set at 9%, but again, it depends on what I'm working on.
When I'm doing serious stippling, I like to set it to regulated, but don't recall what speed. As I've gotten more experience, I've moved it up a bit so don't get too big a stitch.
My favorite feature is a deadbar. My first setup did not have one and each advance required adjusting the height of the back bar - so I really love not having to do that anymore!
