At 12k msl at the windward edge of the roll clouds I cut power to
just above idle, dropped the IAS to between 60 and 65 knots for
minimum sink with about 7 degrees of flaps and there I was a near
equivalent to a glider. In about 20 minutes I was at 17.9k msl. Lift
was still about 300 feet per minute with the engine a little above
idle. The engine was still running smoothly even though it has a Bing
carb with no mixture control. My feet were toasty warm because of the
heater and I was comfortable, in fact more so than in the SparrowHawk
where I would be cold which makes me want to pee often. This was
luxury!
So will I do this again? You bet! I will add another EDS oxygen
system so I can take a passenger. Also I intend, when the wave window
is open, to explore altitudes above 18k up to say 25k. Sometimes it
pays to just think outside the box and do new things!

The wave window is also a "box", so I hope you will think outside of
that one, too, and try some cross-country wave flights. I don't know how
practical that is in the J250, but you could go downwind a long ways,
and motor back the next day when the wind has died down - no lengthy
retrieve.
