Yes, I've been renting skis because I was overwhelmed with the options/choice and wanted to do research before buying (but still overwhelmed). After the first trip in rental boots I went out and bought my own and have been very happy with them. I rented demo skis once (only because the shop didn't have my size in the regular rentals and the difference it made to my trip was huge: sadly I was in a hurry when I dropped the skis off and forgot to make note of the brand/model :/).
So, this is where I run into problems when people ask what kind of skier I am. I seriously don't know. I taught myself to ski aged 7 on a dry ski slope (common in non-snowy climes, like skiing on a very coarse scrubbing brush) watching my older brother, progressed to real snow aged 12 and then took some lessons and skied regularly for a further 6 years. Then I stopped for 20 years and started again three years ago and found, like riding a bike, you never forget. Took a 2 hour private lesson and refined some stuff last year.
I like moguls, don't mind bumps, not really much into powder (but perhaps because I've been using crappy rental skis for the past couple of years and it was tough to ski the fresh stuff), hit the odd (very) small jump if I'm heading past a terrain park! I ski fast, but not aggressively and I suppose I prefer to work on my technique as I go down instead of speed. Skiing through trees scares me (probably shouldn't have watched the video on tree wells).
