I still have to say, a hydraulic failure in an Astar is not a big deal. If you are getting gyrations slowing it down then you have a bad accumulator period. We train them in the hover, 500' hover, slow speed, fast speed, on final approach and never had a problem. I have had 2 for real, again no big deal, although in full disclosure mine were both day VFR.
I guess it is what you are comfortable with.
