Split leap 1/1 (full)
Tour jete 1/2
Despite its high value and despite even being upgraded in 2017 to an E element, the split leap with full turn is an increasingly rare skill on beam because of the difficulty of getting the skill fully around and the likelihood that it will be downgraded to a (basically unusable) split leap with 1/2 turn. Unless those feet are all the way around facing forward again on landing, you’re probably not getting credit. Add that to the potential lack-of-split deductions, and nearly everyone will consider this element more trouble than it’s worth.
That’s why most gymnasts will elect to stick largely with D dance elements like the switch 1/2, willing to eat the deductions that they’re definitely incurring for not hitting 180 on the split because they know they can at least get it around and receive credit for the skill.
