I just finished defretting one of my basses and need flats, but I can't find flats with a High C for a 5 string. Any sets like this, or a 4+1 like elixir does?

I need to order them quick-i am fighting back the impulse to slap some rounds on it to try it out, but i can't ruin my fingerboard!
Thanks!

Edit: If nobody replies with a better idea by the time I get home, I will go with a Rotosound 6 string set.
