I may be reading your post incorrectly, but I wouldn't consider Mello a sport climbing venue, but as an all-rounder it's got a bit of everything. There is some good sport climbing on the Sasso Remmeno as mentioned, loads of quality bouldering further down the valley, and then the main event - the big granite walls. These have a minimal bolting ethic, plus many of the classics are bolt free. Expect well protected cracks and spicy slabs on pristine granite. I used two guides - one for the sport climbing in the valley and on the Sasso, mentioned already, then Solo Granito by the same publisher for the longer routes. In addition to all this, and included in the Solo guide, are the many alpine rock routes above the valley, which usually involve a bivvi or staying in a hut.
