Thank you very much Nikki, I went to your husband's thread and read everyone's comments there (I searched for this topic before I posted but I didn't see any threads that addressed this issue).  It's VERY helpful to hear others' experiences/comments; it helps develop a plan/approach.

And, it's very useful to hear peoples' experiences with different products, like the CVN 300 LH.  I wonder if the broken pcs were made whole by the vendor or did you have to repair them yourself?

Loraine - thank you so much for that advice and sharing your experience.  You are spot on in regard to [generally] lefty's propensity to be ambidextrous [she is]; the leap for her is, this will be the first instrument of any sort she will attempt and it's really not an easy instrument to learn and so naturally she is leaning to what "feels" more comfortable.  I'm really hoping our instructor can guide her into playing "right".  I will share your comments with her this morning and I know it will give her something to consider.

Kevin - lol, having her try my violin is really what caused her to prematurely develop her desire to play lefty.  But I believe you're absolutely right; we need to really take some time to adjust my chin rest and shoulder rest for HER comfort and let her just spend more time bowing it righty.

This has really been helpful; thanks so much for taking time to respond.  She will take her first lesson, using my violin, next Thu.  After she's had a couple lessons, righty, I'll follow up with an update/outcome, if only for the curiosity of those who have been so kind as to respond; but also for anyone in the future who may have the same issue.
