These were my wife's first real ski when she took up skiing at the tender age of 53. She loved them and thought they were much easier than anything else she had tried, and made huge improvement in a hurry. She weighs a little more than you and stands about 5'9". When we got them she was a little concerned that she would not be able to control them...that concern ended in the first 100 yards down the hill. She has since moved on to longer skis of the same basic style. As she has improved (starting to carve) she has started preferring the stability that comes with length while still using a women's specific ski that is easy to bend.
Without seeing you ski it's hard for me to tell if they would be "right" for you. That said, I think you would be pleasantly surprised with how smooth, stable and easy going they are. These aren't squirrelly at speed like some of the shorter skis or rental skis. You might try to find a few reviews of this ski either here or at skidiva.com
I've skied them a couple of times when teaching and though they were super easy going....but then again I weigh 215 and am about an L9.
Please don't hesitate to PM me if you have any more questions
