In reply to Michael Gordon:
Just be careful if you choose the Cyborgs as there was a couple of posts on here asking where u could get replacement front points from as they had ran out stock
Apparently it's a problem BD are aware of but I would consider the fit firstly but also consider the cost and availability of changing the front point.
Petzl have just changed their crampon range so they are more adaptable, so you could buy the Lynx and if u wanted a pair of C2 at a later date you can jet buy the Vasak or similar front section at 2/3 of the price
