Warm welcome to the forum. It is super lovely to have you join here and also a great first post. Lovely to know your thoughts and also it is a pretty cool series to have as a favorite.
As you already stated, there is still a debate about the origins of these. There was an insightful discussion here as well, if you have not checked it out.
Other than that, I wish you success in mastering the set. I hope you can post your pickups and share your favorites as you pick them up. Looking forward.
