So, I bought an NS Omni a month ago for when I travel by airline and want a convenient way to practice while I'm away. Short trips, family vacations, etc. I was pleasantly surprised that getting used to the different scale was no big deal. It took more than 30 minutes to get my intonation accurate, but not much more. Switching back to the URB when I got home took maybe 15 minutes, and most of that was remembering to extend my right arm to place the bow low enough. This was the first time I switched back and forth between the two. I used the Omni for a 10-day vacation. I think this is further evidence that intonation is in your mind. A skill you develop that's transferable to other instruments.
