You were right, the 105 5700 rear derailleur does work with my 12-32 tooth cassette. I put it on today, even with the chain I was using on the 11-28 worked. On the 50 tooth chain ring and 32 tooth the RD was at about a 30 degree angle, it was loose enough to not concern me but I've got another chain ordered. I will leave it a couple links longer and see if the cage is long enough to maintain the tension. Here is some pictures, wanting to get some key words in the post so search engines can better fine it for others to reference.
