I'm hoping to find a softie with a square parachute.

From discussing this with both Don Mayer and the folks at Strong:
A square chute is much more sensitive in deployment (stable and
correct attitude). Both recommend a round emergency chute for
this reason. From discussing my recent bail-out with Don,
I'd probably be dead if I'd had a square chute.

FWIW, from a guy really happy to have had a Strong round emergency chute.

Hope that helps,

PS: I wish I'd had the larger diameter model, landing on rocks
at 11,000 density altitude my descent rate was a bit high...

AFAIK all the chutes for space probes and landing capsules are round.
Sometimes multiple round chutes. This is probably the application that
most needs reliability in adverse conditions above all.
