BGP full feed for testing purposes

Hello, I'm wondering, if there is any public service I can get full BGP feed from for testing purposes. I admin multi-homed AS50242 with two default routes for now (fail-over). I'm going to prepare new routing setup with extended validation so reall full BGP feed would be usefull. Yes, I can ask my upstream provider for it, but I don't want to change settings in production setup. Thanks Regards, Blažej Krajňák
