Thanks for all the updated reviews of the Festivo. I haven't been discouraged about buying one at this point other than the cross-threading issue which I'm sure will be worked out in due time. The only other is the high B natural above the staff (bass clef) which I've read a lot about on compensated horns. Dave has a good suggestion on the cross threading. I have also used very successfully is to turn the cap backwards without any downward force to level it off. It has worked on the Conn I bought used and really seemed to wear back into where it wasn't a problem anymore. My own 24I at times has been a bit of a challenge. Sometimes it has been my own fault.
