Replying to How useful actually are twintips for big mountain

During my recent trip out West I noticed that, well, I wasn't going switch ever unless I was just practicing it on a catwalk or green run. Mind you, I'm pretty bad at skiing switch, but this made me want my next big mountain/"all-mountain" ski to be directional. What actually are the unique capabilities of twintips on big mountain aside from going switch in pow and switch carving down steep groomers?
