Ive noticed there are 2 types of swing clips.
The ones that SUCK are on a bigger swing with yellow ropes, it barely moves and hangs too low to bottom of screen when zoomed more than about 60%. My investigations have led me to believe these are usually older cards.
Then there is the smaller white swing with white ropes that moves more freely and hangs higher up the screen. Those clips are AWESOME!
I am not certain about this but I thought that the larger swing with the yellow ropes was used in the now defunct US studio and the smaller swing with the white ropes is used in the Paris Studio.
This is just an opinion - I could be wrong (in fact I often am)
😉If I am right then I don't think we will be seeing the larger swing any time soon.
EDIT - Based on a random sample of approx 50 or 60 cards (US and non-US girls) with swing clips it looks like I may be right. only the US girls seem to appear on the large swing with yellow ropes.
