In reply to Maximusf:
Having owned quite a few different pairs of crampons here's my take on the last few pairs I owned, I'd generally choose a crampon for the trip / conditions. As a sub point I was on the heavy side typically weighing 90-95 kg or so. I mainly paired these with Freneys
Grivel Rambo IV - fully rigid mono with small secondary point. Definitely rip through on neve more frequently than G14 or mountaineering crampons, harder to climb homoegenous steep ice than true duals as its less stable. I think on aerated ice they can rip a bit more. Better on mixed or featured ice. Come in to their own at UK tech 5 and above. Considered too heavy now a days, they do stiffen up a bit of flex in a B3 boot though ( freneys defo flex a bit)
Grivel G14 dual with toe bail bar- Had to replace the toe bail bar with a different model to improve front point protrusion (compare with other similar crampons). For typical grade UK IV and below mountaineering crampons are on average better IMO. They do rip though a bit more than mountaineering crampons (G12 etc). Great on homogenous ice very stable. Too much hassle to keep changing between mono and dual, pick a fitting and stick to it IMO. Great for Euroice climbing under WI5 (can't comment on grades above that).
Mountaineering crampons G12 / BD Sabretooth. I'd pretty much always buy these with the basket as easier to put on and off and I think its a more bombproof fitting that changes less overtime (with wear) when its right, I think in general its an underated fitting. G12 / G10 I'm not a massive fan of, I think the front point protrusion is too low on most larger boots. Sabretooths are much better in this regard. This style of crampon is by far the best crampon on snow / neve. Climb mixed pretty much as well as G14 in dual mode. Surprisingly good on ice too (given G14 etc are better). These type of crampons are the best all round crampon for grade IV and below in the UK and certainly can be pushed higher.
