What's the longest butterfly race you could swim?

I have done a legal 200 fly in practice. But I think I'd be faster with breaststroke. I would never race a 200 fly though. I haven't raced a 100 fly in four years though I regularly race 50s. There is a chance that I'd take advantage of the Masters rule that allows breaststroke kick....
