The Hyper Guide makes a great crampon for mountaineers, alpinists and guide services. The flexible heel piece resists snow balling and allows a wider variety of boots to fit. The 1-screw adjustment makes it easy for guide services and schools to fit a variety of boot sizes. The Hyper Guide features the same front platform as the Hyper but will not accept the mono-point option.
Three wishes: (1) ability to have a single frontpoint. (2) anti balling plates. (3) umm... well other than that these are great crampons. You'll need to sharpen them right away. They worked well for me.
