Flex filament is probably too flexy. The trouble with PLA is that it essentially starts forming cracks at zero force. If you keep PLA under load it's only a question of how long it takes before it breaks. E.g. making a coat hook from PLA would probably work fine for a long long time, but one day it will break, Even if you just hang a coat from it and never touch it again.
