I'm surprised and trying to understand what happened.
I attached a scan of a contact print I made from a 4x5 negative a little while back. I shot it using Tri-X and used FA-1027. Contact printed. I don't think another developer would have done anything to improve the print. It might have changed the negative slightly in tonality, but usually it's something that can be compensated for to a large extent come printing time. We have so much control over the work flow, both negative processing and printing, by just changing technique, that I usually don't understand why people make such a big deal out of developers. Sure, Edwal 12 has special properties, absolutely, but you can get 80-90% of it by just changing how you shoot and process the film.
