We've hit the 6-month mark of using db:evolve in production here at https://www.hvst.com. This was highly controversial at the time ("wait, you want to NOT use ruby migrations for schema changes? are you insane?!?"), but it turned out to be a huge time-saver. Even the devs who thought I was bat-sh!t crazy at the time now love it.

Anyway, switching to (or back from) db:evolve takes seconds. (Literally 1 line of code needs to be changed.) Give it a try!
