I think the appropriate maneuver for this situation from the Commercial

What about an Immelman? (Granted, not from the Commercial syllabus.) Or
would it require too much altitude?
Several reasons for them not to have used an Immelman:
1) it's a aerobatic maneuver for which the plane was not certified;
2) the pilots were likely untrained to perform such an aerobatic
maneuver;
3) many first attempts at an Immelman turn into an Immel-spin.
Why not a simple steep turn? It's easy to pre-calculate the turn radius for
a given airspeed, bank angle, and crosswind component. In this case, they
had plenty of room if they'd planned and executed the turn properly.
They tried and failed to perform a simple steep turn because they
apparently did not precalculate the maneuver.
The PIC was a PP and presumably not yet schooled in the lazy-8, however
the CFI obviously possessed a Commercial ticket and presumably was
schooled in this maneuver. The lazy-8 is not an aerobatic maneuver and
the Cirrus would have been capable of performing it.

p.s. I have performed lots of lazy-8's in aircraft ranging from
gliders to Turbo Commanders. The maneuver is easy, beautiful and lots
of fun. Go do some today (take an instructor along).
