In reply to UKC Articles:
As an old fart who has been using hexes on the rock since ( before ) they became commercially available, it would have been good if,at least, the following points had been made on the video.
Hexes, rockcentrics, hexcentrics and torque nuts are generally used in larger cracks.
Modern hexes have four placement options, left and right narrow and flare facing and away on sideways.
The greater differential between width options means that hexes often fit well twisted inside pockets.
Camming devices complement hexes ( and nuts ) and are usually better in dry parallel cracks. In icy cracks, uneven cracks or low friction rock the hex often wins out over the cam.
Hexes are lighter than cams and can be hammered to seat in icy cracks.
In 47 years of climbing I have never had to rely on the camming action of a hex, always managing to find some constriction in a crack.
I still marvel at how Supercrack in Indian Creek was put up using old hexes.
