A spring assembly having at least two canted coil spring lengths nested together are disclosed. Two sections of coils of a canted coil spring length can each be positioned between two adjacent coils of another canted coil spring. Each section of the coils of the canted coil spring length includes at least one coil and up to several coils or a plurality of coils. The canted coil spring lengths are nested together to increase the deflection force of the overall spring assembly. The spring assembly having two or more nested spring lengths can be used in connector applications.

The towed roping dummy shock absorption apparatus provides for an apparatus designed to be inserted between a pulling vehicle and a towed roping dummy when practicing team roping from horseback. The apparatus provides for modulation of jerks and forces on the dummy that cause strain on the vehicle, dummy and horse, as well as providing for more consistent speed when being towed.
