Recs are a good way to go, because yeah... 'non-traditional dynamics' can apparently mean ANYTHING.

There's a ST one right now that does actually go with 'omega consistently passes for alpha and retains all canon interests/attributes, alpha is consistently soft/less aggressive (canon compliant), and also wants to be the one getting railed' but it's a jungle out there (only the dangerous jungle animals are just the likelihood of seeing a canon buff, hairy jock guy get called 'princess' and wear skirts and panties)
