Straight 1/1 mount
Stretch jump full mount
Straight jumps are the new gladiator sandal on beam, with their frequency increasing from “none” to “some” in the current quad because of the bonus awarded for jumps from side position on beam, but this new popularity has not extended to the straight jump mounts, which have no footprint in modern elite.
In this case, it’s not for lack of reward. The straight jump with full turn was included in the Great 2017 Mount Upgrade, bumping it up from a useless and pitiful C to a glorious and honorable D, but it has not caught on in the way that a number of other newly-D mounts have that are a little more doable.
