"If we are dependent on having a “good partner”, then we aren’t actually very good dancers."
This was the essence of the blog linked below!
When you are only dancing with partners who are vigorously compensating your low skill level to keep the dance going on you are developing a wrong image about your skill. You probably are not working on the most severe problems in your technique because you are not aware of them, you newer meet your devils.
The whole story!
I still think that the BEST COMBO is when the partners are about at the same level!
