In reply to Jamie B:
The best one is the one that fits best.
In this respect, the Lynx is the best option on paper.
However, what really matters is how a particular crampon fits on your particular boot. The nature of the front bail is secondary.
Unlike the BD and Grivel crampons I've got, I can get the Lynx on both mine and my missus boots without recourse to swapping any bits between crampons to get a fit, etc. That doesn't mean it doesn't take some fiddling to get the perfect fit, but it's acheivable.
They're pricey, but I've seen them for £165 which isn't that much more than the competetors. On the other hand, if a BD or a Grivel crampon fit your boot, then that's the one to go for.
