Like Derek said rent around. I too like the BD cyborg...although the Petzl Lynx is looking good
. I will stay with crampons that have replaceable front points for climbing. Petzl has models that you replace the whole forefoot for about the cost of a new set
. SO price out the parts that will wear and buy within your budget. The Cyborgs are easy to switch around to mono etc. and they have served me well and climb better than my ability. I do have to say though they really do kill me feet if I am standing in them for over 6 hours....could just be me though.
I like the older Quarks but I have yet to get a new set on the ice. All of BD's tools seem to not stick as well as I want...many love them so again : rent around (or borrow a buddy's) and see what you like.
