Grivel Rambo 4

I have used the Rambo line since it started. This revamp is great for fast outfitting and quick tweaks out on the ice. Climbs great, stiff platform, aggressive, and my choice for steep and long ice. The built in flexible anti-bots work great. I don't have any complaints, the best water ice crampons around. If you are going to be walking around a lot or use crampons on approaches then I would opt for something with some flex.
