I didn't upgrade my Vision from 1.08 until Waypoints were released with revision 3.04
I flew knowing about VRS after watching videos and learning the lessons from others. Always have forward momentum when descending and you'll be fine. The implementation of the "2 meters per sec" descent speed is ok, but it takes much longer to bring the craft down.
So its really up to the users preference and how you like to fly. I also noticed that with the limits on descent, the craft acted as though it did not want to descend and fly laterally at the same time . It doesn't act like it wants to do both simultaneously. I never noticed this characteristic in 1.08.
So, if you want the extra performance, and no limitation on descending speed, you can revert your craft back to 1.08. and android app 1.0.38
If you want the waypoint features and additional flight precautions then you'll have to stay with 3.0 and above.
