All good points. Probably the best argument against the twin is that
Cirrus' singles are so damn fast already. I read recently about a
turbonormalizer STC for the SR22 that boosts the cruise up to 200kts.
Not a cheap mod for an extra 15kt on the top end, but the climb is
probably pretty impressive past 8k feet.

That's the main purpose of turbonormalizing, climb performance; and much
better "high and hot" performance.

There's a significant difference between tubronormalizing and
turbosupercharging and evidently that's what Cirrus is going after.
