In reply to Ella Morris:
I mostly only use them in winter, but tend to carry a full set of WC for mixed routes, particularly in the Cairngorms, where I think I'll likely place more of them. If it's more ice then I'll carry my partner's DMM set, as there's less of them for a comparable size range.
The smaller WC sizes can be very useful at times and sometimes work better than a big wire, DMM don't go as small.
Obviously not directly comparable to Peak grit, but for me it's down to how many you have at your disposal per set. If you use them a lot then maybe WC, if you're carrying them in addition to a set of cams as some extra options for wide cracks then maybe DMM.
I think maybe I find the torque nuts slightly easier to get a good camming placement, but I wouldn't say that definitively; others may disagree anyway.
As with any pro they all work well if placed well so it's kinda personal preference really. Cost and availability of reslinging etc are possibly bigger deciding factors
