I, too, mourn the passing of the pre-2008 Montrail Hardrock. Sadly I failed to stock up while they were still available so have had to deal with many "new and improved" trail shoes that quickly proved inadequate. So, I endorse OM's advice; if you find shoes that work for you, stock up. And do it before the marketing department decides to "improve" (cheapen) them to increase profits.
May I walk in beauty.
