Cheap insurance, cheap possible 2nd chance, me thinks.
Just don't factor having one, into how and where you fly.
A few examples of times when I think I would be really glad I have one fitted -
Large bird strike - pelican/ lge eagle / Jaba / emu oops sorry probably no use at that height :-)
Mid air ac collision / passing jet wake perhaps?
Pilot Medical emergency
Caught by an unexpected willy willy / dust devil etc ( may be more trike related as they don't like being inverted )
and I guess
Pilot error could be included - we are human after all and do make poor judgements on occasions
You may notice I haven't included structural failure, flying over inhospitable terrain, bad weather, cloud, engine failure etc
as they are mostly controllable by pilot decisions and actions.
