Cams
They do what it says on the tin. Not exciting exactly but then as much as I might get excited by cams in the shop, when I'm climbing I want them to quietly go about their business without fuss. They do exactly that and are solid and dependable. I could wish that the triggers were a little longer on the smaller sizes to give more reach into deep placements but that is a relatively minor complaint. I also found the double stem can be awkward in a tiny minority of constricted placements but it was very rare and wouldn't stop me choosing 4CUs. I checked all the cams in this review for use with gloves and mitts for winter climbing and the 4CU was slightly harder to use with my gloves on but, oddly, the only one I could reliably use wearing mitts. To cover a range from 19-100mm you would have 7 units weighing a total of 983g
