What is this about round vs ram/square? I thought it was generally
accepted that ram/square give more control and lower descent rates,
but are less suitable for glider emergency chutes because they work
reliably only if you are the right way up etc. when you pull them.

Whereas it used to be said that round ones may give no or less control
and a higher descent rate (for a given area), and you may get broken
ankles, but they are better life savers because they deploy more
quickly and reliably when used by untrained glider pilots in emergency
when you may deploy them in far from the best attitude.

True, false, or what?
