with several ice climbing sessions I was able to test and compare different devices - and have decided on the Grivel X-Monster because I had the best feeling with this device and trust him most. For other devices, I was uncertain whether to keep or break out again when I am working myself up. The X-shaped monster is very ergonomic and designed. If you install the supplied rubber grips between blade and handle has one from the lower part of the handle to just below the blade always a very good gripping ability and can bring train on the device from different angles. Perhaps the better feeling also comes about because the shaft of the X-Monster - is made of a metal plate and not from a tube, as with all other devices - more simplistic. For comparison, I had my old ice tools with strongly curved stem and hand straps. So I need twice as long to climb a 30-meter high icefall and need twice as much strength in the forearms. In addition, even with the Black Diamond Fusion and the Petzl Nomic. These are of course also pointed devices, especially with the Nomic can super hit but overall the X-Monster the best device for me personally.
