One of the take home messages from this thread is that there isn't really a right way to do the kick. In almost all of these videos by legit professionals, they are doing it differently.
In retrospect, I still like my lean back instead of slipping with weight forward way of doing the kick.
I've seen and heard step to the inside, to the outside, rotate 90, rotate 180, spin all the way around, never spin all the way around, and so on and on.
I do appreciate all of the advice. I think the new way of kicking I got from this thread, slipping and keeping the weight forward on the low kick, and standing up tall and not leaning back on the mid kick are really cool and valuable. I've been using them in sparring a little bit and have a legit MT instructor in real life now to help.
I'll post one last video of me kicking so that you can see that it still isn't great, but that I have been trying to apply it and then I'll let this thread die.
Thank you all for the help. I really appreciate it.
