Yes, the spoke cut and custom bent works fine, but you need to carefully prepare it in advance to match the length of spokes in your wheel. Another alternative is to carry one of the flexible Kevlar fiber spokes that can be adjusted to the needed length. As with the 'z-end' spokes, these can also be installed without removing the wheel from the bike. More expensive, but only one of them needs to be carried for a group of riders and the fiber spoke can be reused when you get a regular spoke of the right length.
