Oh, very interesting, Empyrean, I had never seen the leg switch version. Good research!
The main thing I noticed is that with the leg switch version, the need for the body twist during the fall is not necessary and there's no turning, but without the leg switch the whole body passes across the pole before securing in the Scorpio. I don't understand how the lady doing the leg switch Holly Drop was able to avoid slamming her side into the pole!
I don't know if I would consider that a Holly Drop for sure. It's a very impressive and pretty move, but the technique and landing are different than the original one. If I am not mistaken about the origins of the Holly Drop, it was first seen on YouTube being performed by a lady identified as "Tattooed Hollie," on a channel that I think is called "mrandmrsburroughs" or something of the sort. Karol of the REDKE71 YouTube channel and our current reigning Miss USPDF East Coast adopted and perfected the move, and named it the Holly Drop after Tattooed Hollie. If anyone knows the Holly Drop history better, please feel free to correct me.
Some key points about the leg switch variation: 1.) the leg switch was performed before this lady released the pole. While her top arm was still on the pole, she placed her lower hand on the pole too, performed the leg swtich, and dropped after hooking with the second leg. So except for some possible rib bruising, it sounds pretty safe. But nonetheless, this modified Holly Drop is a drop from a lower leg hook, instead of an upper leg hook. 2.) taking into consideration that the legs have to be swtiched before the hands are released, dropping out of a knee hold or Cupid/Star would be obsolete. It might be more intuitive to do this variation from a modified pole sit, a plank, or some other position where the legs are already placed where they would need to be located in order to drop into a Scorpio from the lower leg instead of the higher leg.
God, I feel like such a Poindexter. LOL! Geez, without a pole I'd have no life. Just more fuel for my poisonously analytical mind.
