Replying to Good set-up for my mom?

Planning to surprise my mom with some skis next fall as an early Christmas present. She currently rides some crappy head skis that are like 149CM long, which is terribly short.

She's 5'5 130ish, one hell of a skier, on ski patrol, and her current skis are definitely holding her back. She is more of groomer skier now because she is getting into her 50's, but we take a few trips out west each year with occasional pow in the midwest.

I'm very interested in ON3P Jessie's since I've had such a great experience with the company, but open to more recommendations. What is a good length?
