Living in a vertically challenged part of the ski world I can make fun out of a mtn with only 600' of vertical for day trips, but ideally 2000' or more is preferred when I make more ambitious ventures to New England or out West. Typically most of us think - the more vertical the better, but in reality most big resorts ski in 1000-2000 vertical chunks due to natural terrain breaks or lift infrastructure economies. It can often be awkward to strive for more. Off the top of my head, however, I can recall pleasant memories of skiing sizable verticals repeatedly from one ski lift at places like Aspen/Ajax Mtn CO (gondola), Snowbird UT (tram), Killington VT (Skyeship gondola) all in range of ~3000', and Kirkwood CA (Wagonwheel or Cornice chairs), Wildcat NH (high speed quad), and Stratton (gondola) all in range of ~2000. Could come up with many more fine examples if I pondered longer.
In North America there aren't too many places where you can easily ski REAL big lift-served verts in the 4-5k range; Jackson Hole, Big Sky and Whistler come to mind, but I haven't been to those three. I have skied some places in Europe with comparable verts. Under the right conditions this is great fun and gives a wonderful feeling of freedom from the yo-yo syndrome of frequent lift rides between quick bursts of skiing many of us normally experience, but once you start talking those kind of vertical differences the significant variability in weather and conditions between summit and base can reduce the motivation or fun in making complete top to bottom runs on a repeated basis all day long. You wind-up spending much of your time where the best 1000-2000 vertical feet of snow lies or shortest lift lines are found.
Here are some more thoughts on the fun of big vert skiing/lifts: http://www.dcski.com/articles/view_a...mode=headlines
Mt. Rose may "only" have 1800 vertical feet, but given the proximity to other sizable mtns around Tahoe I don't think their vertical drop should be a limiting factor for those who might visit that region. Whereas it might be an issue if visiting a comparably sized mountain such as Ski Santa Fe NM with a less dense concentration of big ski mtns nearby to visit on successive days.
Bottom line - it's all good.
