I am on my Heq5 Mike. Probably won't compare at all nicely to your smooth new hypertuned 6 though! I've still never conclusively proved how much it helps, but is SHOULD. Some pics that have come out particularly tight were during PEC runs, but tthat was also at a dark sky site with very good seeing.
For my Newt on the heq5, I think 80-90% of what matters is good alignment and balance (and cable management, and luck, and no wind, and tracking on the east side, and not having the object too low, and tweaking the guide settings, and good seeing, and .........)
