If you're truly on the beginner side of intermediate, and aren't exploring powder much yet, then I'd go even narrower with a Nordica Astral 84, Head Total Joy, Blizzard Black Pearl 82, Rossignol Experience 84W. Something along those lines that is a bit narrower but certainly a major step up from a rental ski that will give you confidence and handle some off-piste stuff, too. Most of those I mentioned above can be found fairly inexpensively. I know Ski Essentials had the Astra 84 for around $200, but I think they were sold out of most lengths.
I can highly recommend that as well if you don’t ski much powder. The Astral 84 is a super fun ski, very forgiving so would be great to improve on. They are great on groomers and fun in bumps too. I bought a pair for around $200 last season (without bindings) to play on firmer days and work on bumps and I’m an advanced skier. Just don’t skimp on the sizing because they are a softer ski.
