I miss the old days when a couple danced together, not just near each other ;-P Who would've thunk it would be twice as silly for BOTH people to be looking for their next partner at the same time. lol I can't help but think this "evolution" was mostly about more teachers and coaches selling more lessons and coaching.
Actually you can built in a little 3d in Chasse, at least if you dance it from PP and let it follow by a Natural Turn. You can achieve it by using a little swaying/ tilting action between the start after pp just till after the closing the feet. This movement can be enhanced by hovering while closing the feet. Wondering what i mean. Every modern real advanced competition couple use this in this version of the Chasse. Not that you see this version that much nowadays.
