Pace: My comment was regarding your fear about entanglement.
Be careful with general statements including being able to recover at altitude. One chute pull involved a CFI and aerobatic pilot who was at something like 16,000'. He was in clear air but over an undercast. The next thing he knew he was upside down in the clouds. The speculation involves rapidly building clouds which can rise at 5000'/minute. I back his decision to pull rather than try to recover in the clouds and over mountains. An interesting side note was that the Christmas ornaments in the luggage compartment survived intact.
